Berbagai polemik yang berkepanjangan mengenai <a href="http://www.ujiannasional.info/" target="_blank">Ujian Nasional</a> di Indonesia tampak baik bagi demokrasi di negeri ini. Tapi satu hal yang jangan terlupa bahwa siswa peserta UN jangan sampai dibuat ragu atau takut tentang kepastian Ujian Nasional sebagai sarana untuk mengukur kemampuan mereka di bangku sekolahnya. Untuk tahun 2012 Menteri Pendidikan dan Kebudayaan Mohammad Nuh memastikan pemerintah tetap akan menggelar ujian nasional tahun 2012. Ujian nasional dijadwalkan berlangsung pada April 2012. Oleh karena itu kami berusaha membantu para siswa/i peserta Ujian Nasional di manapun berada untuk menyediakan Latihan Soal UN 2012 yang memenuhi standar, semoga upaya kami dapat memberikan tambahan berharga bagi para siswa, para guru, orang-tua siswa, dan masyarakat pada umumnya.<span class="fullpost"><br /> <br />Mendikbud mengatakan saat ini perdebatan mengenai UN sudah selesai. Ia menuturkan, ada empat kunci pelaksanaan UN yang baik atau kredibel. Pertama, dijamin keamanan dan kerahasiaannya. Karena jika berkasnya bocor, maka kredibilitas UN itu sudah berkurang, bahkan hilang. Kedua, dari sisi ketepatan distribusi, harus tepat waktu, tepat jumlah, dan tepat bahan yang mau diuji. Ketiga, pada hari pelaksanaan harus dijamin kelancarannya. Jangan sampai soal sudah ada semua tapi soal ujian yang dibagikan salah. Dan, keempat, dalam sistem evaluasi harus dipastikan agar nilai rapor bisa menjamin bahwa nilai itu mencerminkan kemampuan sang anak.<br /> <br />Ok berarti Ujian Nasional sudah dipastikan bakal digelar sesuai <a href="http://www.ujiannasional.info/2012/01/jadwal-ujian-nasional-2012.html" target="_blank">Jadwal Ujian Nasional 2012</a> yang telah ditetapkan secara resmi oleh Pemerintah.

Menteri Pendidikan dan Kebudayaan (Mendikbud) Mohammad Nuh mengingatkan bahwa kepala daerah jangan memanfaatkan UN sebagai alat politik dan menekan kepala sekolah agar siswanya lulus 100 persen. Hal tersebut ditegaskan oleh Mendikbud dalam acara Deklarasi / Ikrar Ujian Nasional Jujur, Berprestasi dan Pendidikan Anti Korupsi di Jambi, Kamis (9/2).<br /> <br />"Sudah bukan eranya bupati dan walikota menekan kepala sekolah agar lulus 100 persen." tegas Menteri Nuh. Tekanan kepala daerah kepada kepala sekolah agar tingkat kelulusan siswanya 100 persen kerap berujung pada berbagai pelanggaran dan kecurangan. Menteri Nuh mengungkapkan, bahwa tekanan yang begitu kuat kepada kepala sekolah bisa saja mendorongnya membuat instruksi ke guru-guru untuk berbuat curang. Kecurangan yang sering terjadi adalah guru-guru menyebar kunci jawaban kepada siswanya.<br /> <br />Menteri Nuh berharap tidak ada lagi kasus kebocoran soal UN dan sontek masal seperti yang terjadi tahun kemarin, entah itu didasari tekanan kepala dinas ataupun sebab-sebab lain. Menteri mengajak semua pemangku kepentingan pendidikan bersama-sama mendukung UN yang jujur dan berkualitas. "Mari jalankan Ujian Nasional dengan jujur." ajak Menteri Nuh.<br /> <br />Dalam kunjungannya ke SMP Negeri 14 Kota Jambi, Jumat (10/2), Menteri mengajak siswa-siswa agar tenang menghadapi UN dan mengutamakan kejujuran. "Jangan takut menghadapi UN, itu kan pelajaran yang kalian pelajari sehari-hari." pesan Menteri kepada siswa-siswa SMP tersebut. <br /><br /></span><br /></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-76566023412590548472011-10-07T06:56:00.000-07:002011-10-07T07:00:35.309-07:00The integrationUN with SNMPTN<div align="justify"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/-_HjkF9w1wv8/To8F6h5X7UI/AAAAAAAAAC8/PWpEAvWKOAo/s1600/un-2012.jpg"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 223px; height: 136px;" src="http://3.bp.blogspot.com/-_HjkF9w1wv8/To8F6h5X7UI/AAAAAAAAAC8/PWpEAvWKOAo/s320/un-2012.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5660749759717567810" /></a>The 2012 national examination results (UN) can be integrated to enter public universities (PTN). Moreover, it has become a collective agreement.<br /><br />This is expressed by educational researchers from the Center for Educational Assessment Ministry of National Education (Ministry of National Education), Drs. Safari, M., P.A.U. told reporters on the sidelines of a workshop in Bandung education Vocational School (SMK) District 9, Jln. Soekarno-Hatta Jakarta, Wednesday (28 / 9).<br /><span class="fullpost"><br /><br />"But certainly whether or not the policy of the government, I can not be sure," said Safari.<br /><br />It is said, wants the UN to integrate the value of PT, because the UN was the same (standard). While public universities have not been standardized exam results. "This is the basis, we want the UN could be admission to state universities," he said.<br /><br />According to him, in the implementation, the UN has been running smoothly and perfectly. That need to be perfected, is the only technical problems, especially for entry into the PTN.<br /><br />"PTN must accept, because this discourse has been discussed and agreed between the parties," he added.<br /><br />According to him, from the research results, implementation of the UN in Indonesia the envy of other countries, especially from the technical side of implementation. In addition, the UN is the same standard of value, namely 5.5 standard value even if the UN is still relatively small.<br /><br />"In other countries, like Malaysia and Singapore standardized test scores of at least seven," he said.<br /><br />Safari said the UN to measure students' ability to be implemented nationally. While the material being tested is at least the lesson has been taught in school.<br /><br />"There's no way the material being tested is a lesson not taught in school," he said.<br /><br />The existence of the cons of this examination, because the material in accordance with the UN is not being taught. Safari said the school should introspection, because the teacher did not teach properly.<br /><br />Separately, Head of Education Jabar, Prof. Dr. Wahyudin Zarkasyi said the UN to integrate the results into the PTN was already discussed and will be piloted in 2012. However, there are some technical implementation should be enhanced.<br /><br />"Implementation of the UN Special mechanisms are integrated into state universities," he added.<br /><br />Wahyudin claimed to strongly support the UN can be a prerequisite for entry PTN. "But there are some that must be perfected," he said.<br /><br />While Chairman of the Board of Education of Bandung, Kusmeni Hartadji rate, pemeritah not yet ready to integrate the UN to be a prerequisite get into state universities. In addition to the implementation of the system is not perfect, it still happens dishonesty among students and supervisors in the implementation of the UN. </span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-3200564604519791682011-03-09T01:24:00.000-08:002011-10-07T06:45:30.780-07:00Quadratic equations Exam<div align="justify">In mathematics, a quadratic equation is a polynomial equation of the second degree. <br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important!<span class="fullpost"> <br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><b>Download for Vocational School - Technology Program</b><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-mathematics-for-vocational.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/mathematics-for-vocational-school.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br /><b>Download for Vocational School - Accountancy Program</b><br /><a href="http://ihhi.blogspot.com/2011/03/mathematics-for-vocational-school_2505.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-mathematics-for-vocational_9820.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br /><b>Download for Vocational School - Tourism Program</b><br /><a href="http://ihhi.blogspot.com/2011/03/mathematics-for-vocational-school_08.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-mathematics-for-vocational_1003.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />The constants a, b, and c, are called respectively, the quadratic coefficient, the linear coefficient and the constant term or free term.

Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. A sequence is a discrete function.<br /><br />For example, (C, R, Y) is a sequence of letters that differs from (Y, C, R), as the ordering matters. Sequences can be finite, as in this example, or infinite, such as the sequence of all even positive integers (2, 4, 6,...). Finite sequences are sometimes known as strings or words and infinite sequences as streams. The empty sequence ( ) is included in most notions of sequence, but may be excluded depending on the context.<span class="fullpost"><br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important! <br /><br /><br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><a href="http://ihhi.blogspot.com/2011/03/rows-and-rows-of-mathematics.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-rows-and-rows-of.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br /><b>Download for Vocational School (SMK)</b><br /><a href="http://ihhi.blogspot.com/2011/03/mathematics-for-vocational-school_4344.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-mathematics-for-vocational_9127.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />A series is the sum of the terms of a sequence.

Since adding is generally easier than multiplying, this led to the rapid adoption of logarithms for calculations after their invention by John Napier in the early 17th century. For such computational purposes, the logarithm to base b = 10 (common logarithm) was primarily used. The natural logarithm uses the constant e (approximately 2.718) as its base, and is especially widespread in calculus. The binary logarithm uses base b = 2 and primarily aids computing applications.<span class="fullpost"><br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important! <br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><a href="http://ihhi.blogspot.com/2011/03/math-logarithm.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-math-logarithm.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />Logarithmic scales reduce wide-ranging quantities to smaller scopes. For example, the Richter scale uses the common logarithm to measure the amplitude of seismic events. Logarithms are commonplace in scientific formulas, measure the complexity of algorithms and of fractals, and appear in formulas counting prime numbers. They describe musical intervals, inform some models in psychophysics and can aid in forensic accounting.<br />The complex logarithm is the inverse of the exponential function applied to complex numbers and generalizes the logarithm to complex numbers. The discrete logarithm is another variant; it has applications in public-key cryptography.<br /><br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-25650758570554489122011-03-09T01:17:00.000-08:002011-10-07T06:47:20.961-07:00Three-dimensional Exam<div align="justify">Three-dimensional space is a geometric model of the physical universe in which we live. The three dimensions are commonly called length, width, and depth (or height), although any three directions can be chosen, provided that they do not lie in the same plane.<br />In physics, our three-dimensional space is viewed as embedded in 4-dimensional space-time, called Minkowski space (see special relativity). The idea behind space-time is that time is hyperbolic-orthogonal to each of the three spatial dimensions.<span class="fullpost"><br />In mathematics, analytic geometry (also called Cartesian geometry) describes every point in three-dimensional space by means of three coordinates. Three coordinate axes are given, usually each perpendicular to the other two at the origin, the point at which they cross. They are usually labeled x, y, and z. Relative to these axes, the position of any point in three-dimensional space is given by an ordered triple of real numbers, each number giving the distance of that point from the origin measured along the given axis, which is equal to the distance of that point from the plane determined by the other two axes.<br />Other popular methods of describing the location of a point in three-dimensional space include cylindrical coordinates and spherical coordinates, though there are an infinite number of possible methods.<br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important! <br /><br /><br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><a href="http://ihhi.blogspot.com/2011/03/three-dimensional-mathematical.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-three-dimensional.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />Another mathematical way of viewing three-dimensional space is found in linear algebra, where the idea of independence is crucial. Space has three dimensions because the length of a box is independent of its width or breadth. In the technical language of linear algebra, space is three dimensional because every point in space can be described by a linear combination of three independent vectors. In this view, space-time is four dimensional because the location of a point in time is independent of its location in space.<br />Three-dimensional space has a number of properties that distinguish it from spaces of other dimension numbers. For example, at least 3 dimensions are required to tie a knot in a piece of string. The understanding of three-dimensional space in humans is thought to be learned during infancy using unconscious inference, and is closely related to hand-eye coordination. The visual ability to perceive the world in three dimensions is called depth perception.<br />In mathematics, a relation is used to describe certain properties of things. That way, certain things may be connected in some way; this is called a relation. Formally, a relation is a set of n-tuples of equal degree. Thus a binary relation is a set of pairs, a ternary relation a set of 3-tuples, and so forth. A ternary relation however is always expressable as two binary relations. Specifically in the context of functions, this is known as currying.<br />Particularly concerning binary relations, the set of all the starting point is called the domain and the sets of the ending points is the range. The domain is the x's , and the range is the y's.<br />An example for such a relation might be a function. Functions associate keys with values. The set of all functions is a subset of the set of all relations - a function is a relation where the first value of every tuple is unique through the set.<br />Other well-known relations are the Equivalence relation and the Order relation. That way, sets of things can be ordered: Take the first element of a set, it is either equal to the element looked for, or there is an order relation that can be used to classify it. That way, the whole set can be classified (compared to some arbitrarily chosen element).<br />Relations can be transitive. One example of a transitive relation is "smaller-than". If X "is smaller than" Y, and Y is "smaller than" Z, then X "is smaller than" Z<br />Relations can be symmetric. One example of a symmetric relation is "is equal to".<br />Relations can be reflexive. <br />A reflexive relation is "smaller than or equal".<br /><br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-11697847749197131112011-03-09T01:15:00.000-08:002011-10-07T06:47:20.961-07:00Derivative Exam<div align="justify">In calculus, a branch of mathematics, the derivative is a measure of how a function changes as its input changes. Loosely speaking, a derivative can be thought of as how much one quantity is changing in response to changes in some other quantity; for example, the derivative of the position of a moving object with respect to time is the object's instantaneous velocity. Conversely, the integral of the object's velocity over time is how much the object's position changes from the time when the integral begins to the time when the integral ends.<span class="fullpost"><br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important! <br /><br /><br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><a href="http://ihhi.blogspot.com/2011/03/mathematical-derivation.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-mathematical-derivation.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />The derivative of a function at a chosen input value describes the best linear approximation of the function near that input value. For a real-valued function of a single real variable, the derivative at a point equals the slope of the tangent line to the graph of the function at that point. In higher dimensions, the derivative of a function at a point is a linear transformation called the linearization.The process of finding a derivative is called differentiation. The reverse process is called antidifferentiation. The fundamental theorem of calculus states that antidifferentiation is the same as integration. Differentiation and integration constitute the two fundamental operations in single-variable calculus.<br /><br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-63441101823466560382011-03-09T01:13:00.000-08:002011-10-07T06:47:20.961-07:00Statistics Exam<div align="justify">Mathematical statistics is the study of statistics from a mathematical standpoint, using probability theory as well as other branches of mathematics such as linear algebra and analysis. The term "mathematical statistics" is closely related to the term "statistical theory" but also embraces modelling for actuarial science and non-statistical probability theory, particularly in Scandinavia.<br />Statistics deals with gaining information from data. In practice, data often contain some randomness or uncertainty. Statistics handles such data using methods of probability theory.<span class="fullpost"><br />Statistical science is concerned with the planning of studies, especially with the design of randomized experiments and with the planning of surveys using random sampling. The initial analysis of the data from properly randomized studies often follows the study protocol.<br />Of course, the data from a randomized study can be analyzed to consider secondary hypotheses or to suggest new ideas.

In fact, there are two broad categories of probability interpretations, whose adherents possess different (and sometimes conflicting) views about the fundamental nature of probability:<br />Frequentists talk about probabilities only when dealing with experiments that are random and well-defined. The probability of a random event denotes the relative frequency of occurrence of an experiment's outcome, when repeating the experiment. Frequentists consider probability to be the relative frequency "in the long run" of outcomes.<br />Bayesians, however, assign probabilities to any statement whatsoever, even when no random process is involved. Probability, for a Bayesian, is a way to represent an individual's degree of belief in a statement, or an objective degree of rational belief, given the evidence.<br /><br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-52623096399622001092011-03-09T01:11:00.000-08:002011-10-07T06:47:20.962-07:00Relation and Function Exam<div align="justify">In mathematics, a relation is used to describe certain properties of things. That way, certain things may be connected in some way; this is called a relation. It is clear, that things are either related, or they are not, there are no in-betweens.<br /><br />Formally, a relation is a set of n-tuples of equal degree. Thus a binary relation is a set of pairs, a ternary relation a set of 3-tuples, and so forth. A ternary relation however is always expressable as two binary relations. Specifically in the context of functions, this is known as currying.<span class="fullpost"><br /><br />Particularly concerning binary relations, the set of all the starting point is called the domain and the sets of the ending points is the range. The domain is the x's , and the range is the y's.<br /><br />An example for such a relation might be a function. Functions associate keys with values. The set of all functions is a subset of the set of all relations - a function is a relation where the first value of every tuple is unique through the set.<br /><br />Other well-known relations are the Equivalence relation and the Order relation. That way, sets of things can be ordered: Take the first element of a set, it is either equal to the element looked for, or there is an order relation that can be used to classify it. That way, the whole set can be classified (compared to some arbitrarily chosen element).<br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important! <br /><br /><br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><a href="http://ihhi.blogspot.com/2011/03/mathematical-function.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-mathematical-function.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />A function, in a mathematical sense, expresses the idea that one quantity (the argument of the function, also known as the input) completely determines another quantity (the value, or the output). A function assigns exactly one value to each input of a specified type. The argument and the value may be real numbers, but they can also be elements from any given sets: the domain and the codomain of the function. An example of a function with the real numbers as both its domain and codomain is the function f(x) = 2x, which assigns to every real number the real number with twice its value. In this case, it is written that f(5) = 10.<br /><br />In addition to elementary functions on numbers, functions include maps between algebraic structures like groups and maps between geometric objects like manifolds. In the abstract set-theoretic approach, a function is a relation between the domain and the codomain that associates each element in the domain with exactly one element in the codomain. An example of a function with domain {A,B,C} and codomain {1,2,3} associates A with 1, B with 2, and C with 3.<br /><br />There are many ways to describe or represent functions: by a formula, by an algorithm that computes it, by a plot or a graph. A table of values is a common way to specify a function in statistics, physics, chemistry, and other sciences. A function may also be described through its relationship to other functions, for example, as the inverse function or a solution of a differential equation. There are uncountably many different functions from the set of natural numbers to itself, most of which cannot be expressed with a formula or an algorithm. Functions with numerical outputs may be added and multiplied, yielding new functions. Collections of functions with certain properties, such as continuous functions and differentiable functions, usually required to be closed under certain operations, are called function spaces and are studied as objects in their own right, in such disciplines as real analysis and complex analysis. An important operation on functions, which distinguishes them from numbers, is the composition of functions.<br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-12750522446168692222011-03-09T01:08:00.000-08:002011-10-07T06:47:20.962-07:00Matrix Exam<div align="justify">In mathematics, a matrix (plural matrices, or less commonly matrixes) is a rectangular array of numbers, such as<br /><br />An item in a matrix is called an entry or an element. The example has entries 1, 9, 13, 20, 55, and 6. Entries are often denoted by a variable with two subscripts, as shown on the right; thus in the example above, a2,1 = 20. Matrices of the same size can be added and subtracted entrywise and matrices of compatible sizes can be multiplied. These operations have many of the properties of ordinary arithmetic, except that matrix multiplication is not commutative, that is, AB and BA are not equal in general. Matrices consisting of only one column or row define the components of vectors, while higher-dimensional (e.g., three-dimensional) arrays of numbers define the components of a generalization of a vector called a tensor. Matrices with entries in other fields or rings are also studied.<span class="fullpost"><br />Matrices are a key tool in linear algebra. One use of matrices is to represent linear transformations, which are higher-dimensional analogs of linear functions of the form f(x) = cx, where c is a constant; matrix multiplication corresponds to composition of linear transformations. Matrices can also keep track of the coefficients in a system of linear equations. For a square matrix, the determinant and inverse matrix (when it exists) govern the behavior of solutions to the corresponding system of linear equations, and eigenvalues and eigenvectors provide insight into the geometry of the associated linear transformation.<br /><br />We are very grateful for your visit on this blog, please you may download the files you need here and of course free and is very important! <br /><br /><br /><h2>Download Theory of Mathematics for School Exam</h2><br /><b>Download for Science Program</b><br /><a href="http://ihhi.blogspot.com/2011/03/matrix-math.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-matrix-math.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br /><b>Download for Social Program</b><br /><a href="http://ihhi.blogspot.com/2011/03/matrix-math-for-sma-non-science-program.html" target="_blank">Download Theory of Mathematics </a><br /><a href="http://ihhi.blogspot.com/2011/03/questions-of-matrix-math-for-sma-non.html" target="_blank">Download Exam Questions of Mathematics</a><br /><br />Matrices find many applications. Physics makes use of matrices in various domains, for example in geometrical optics and matrix mechanics; the latter led to studying in more detail matrices with an infinite number of rows and columns. Graph theory uses matrices to keep track of distances between pairs of vertices in a graph. Computer graphics uses matrices to project 3-dimensional space onto a 2-dimensional screen. Matrix calculus generalizes classical analytical notions such as derivatives of functions or exponentials to matrices. The latter is a recurring need in solving ordinary differential equations. Serialism and dodecaphonism are musical movements of the 20th century that use a square mathematical matrix to determine the pattern of music intervals.<br />A major branch of numerical analysis is devoted to the development of efficient algorithms for matrix computations, a subject that is centuries old but still an active area of research. Matrix decomposition methods simplify computations, both theoretically and practically. For sparse matrices, specifically tailored algorithms can provide speedups; such matrices arise in the finite element method, for example.<br /><br /><br /><br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-85414317206576393052011-03-09T01:07:00.000-08:002011-10-07T06:47:20.962-07:00Integral Exam<div align="justify">Integral is an important concept in mathematics and, together with differentiation, is one of the two main operations in calculus.

A rigorous mathematical definition of the integral was given by Bernhard Riemann. It is based on a limiting procedure which approximates the area of a curvilinear region by breaking the region into thin vertical slabs. A line integral is defined for functions of two or three variables, and the interval of integration [a, b] is replaced by a certain curve connecting two points on the plane or in the space. In a surface integral, the curve is replaced by a piece of a surface in the three-dimensional space. Integrals of differential forms play a fundamental role in modern differential geometry. These generalizations of integrals first arose from the needs of physics, and they play an important role in the formulation of many physical laws, notably those of electrodynamics. There are many modern concepts of integration, among these, the most common is based on the abstract mathematical theory known as Lebesgue integration, developed by Henri Lebesgue.<br /></span></div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-75617377937228531412011-03-09T01:05:00.000-08:002011-10-07T06:47:20.962-07:00Limit Exam<div align="justify">In mathematics, the concept of a "limit" is used to describe the value that a function or sequence "approaches" as the input or index approaches some value.

A trapezoid with vertices ABCD is denoted ABCD.<br /><br />This article uses the term trapezoid in the sense that is current in the United States (and sometimes in some other English-speaking countries). Readers in the United Kingdom and Australia should read trapezium for each use of trapezoid in the following paragraphs. In all other languages using a word derived from the Greek for this figure, the form closest to trapezium (e.g. French 'trapèze', Italian 'trapezio', German 'Trapez', Russian 'трапеция') is used.<br /><br />The term trapezium has been in use in English since 1570, from Late Latin trapezium, from Greek trapezion, literally "a little table", diminutive of trapeza "table", itself from tra- "four" + peza "foot, edge". The first recorded use of the Greek word translated trapezoid (τραπεζοειδη, table-like) was by Marinus Proclus (412 to 485 AD) in his Commentary on the first book of Euclid’s Elements.<br /><span class="fullpost"><br />There is also some disagreement on the allowed number of parallel sides in a trapezoid. At issue is whether parallelograms, which have two pairs of parallel sides, should be counted as trapezoids. Some authors define a trapezoid as a quadrilateral having exactly one pair of parallel sides, thereby excluding parallelograms. Other authors define a trapezoid as a quadrilateral with at least one pair of parallel sides, making the parallelogram a special type of trapezoid (along with the rhombus, the rectangle and the square). The latter definition is consistent with its uses in higher mathematics such as calculus. The former definition would make such concepts as the trapezoidal approximation to a definite integral be ill-defined.<br /><br /><b><a href="http://ihhi.blogspot.com/2011/03/trapezoid-for-junior-high-school.html" target="_blank">Download Theory of Mathematics UN according to grid UN 2010/2011</a></b><br /><b><a href="http://ihhi.blogspot.com/2011/03/questions-of-trapezoid-for-junior-high.html" target="_blank">Download the sample of Questions</a></b><br /><br />In North America, the term trapezium is used to refer to a quadrilateral with no parallel sides. The term trapezoid has been defined as a quadrilateral without any parallel sides in Britain and elsewhere, but this does not reflect current usage (the Oxford English Dictionary says “Often called by English writers in the 19th century”).<br />According to the Oxford English Dictionary, the trapezoid as a figure with no sides parallel is the sense for which Proclus introduced the term; it is retained in the French "trapézoïde", German "trapezoïd", and in other languages. A trapezium in Proclus' sense is a quadrilateral having one pair of its opposite sides parallel. This was the specific sense in England in 17th and 18th centuries, and again the prevalent one in recent use. A trapezium as any quadrilateral more general than a parallelogram is the sense of the term in Euclid. The sense of a trapezium as an irregular quadrilateral having no sides parallel was the usual sense in England from c1800 to c1875, but is now rare. This article uses the term trapezoid in the sense that is current in the USA and some other English-speaking countries. Readers in the UK should read trapezium for each use of trapezoid in the following paragraphs. <br />There is also some disagreement on the allowed number of parallel sides in a trapezoid.

Other authors define a trapezoid as a quadrilateral with at least one pair of parallel sides, making a parallelogram a special type of trapezoid. <br /><br /></span> </div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-90642873559937364102011-03-07T20:47:00.000-08:002011-10-07T06:47:20.963-07:00Triangle for Junior High School<div align="justify"><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/-ERj8lY4Ut2Y/TXW0VsRcvAI/AAAAAAAAATA/0uhZWXTgzNU/s1600/Segitita.png" imageanchor="1" style="clear:left; float:left;margin-right:1em; margin-bottom:1em"><img border="0" height="149" width="175" src="http://2.bp.blogspot.com/-ERj8lY4Ut2Y/TXW0VsRcvAI/AAAAAAAAATA/0uhZWXTgzNU/s320/Segitita.png" /></a></div>A triangle or trigon is a two dimensional geometric object that has the specific qualities of having three straight sides that intersect at three vertices. <br />The sum of the internal angles that exist at the vertices always total the same number for every triangle—180 degrees, or π radians. <br />In Euclidean geometry, any three non-collinear points determine a unique triangle and a unique plane. <br />Types of triangles <br />By relative lengths of sides <br />Triangles can be classified according to the relative lengths of their sides: <br />In an equilateral triangle, all sides are the same length. An equilateral triangle is also a regular polygon with all angles 60°. <br />In an isosceles triangle, at least two sides are equal in length. An isosceles triangle also has two equal angles: the angles opposite the two equal sides. <br />In a scalene triangle, all sides and internal angles are different from one another. <br />By internal angles <br />Triangles can also be classified according to their internal angles, measured here in degrees. <br /><br /><span class="fullpost"><br /><br /><b><a href="http://ihhi.blogspot.com/2011/03/triangle-for-junior-high-school.html" target="_blank">Download Theory of Mathematics UN according to grid UN 2010/2011</a></b><br /><b><a href="http://ihhi.blogspot.com/2011/03/questions-of-triangle-for-junior-high.html" target="_blank">Download the sample of Questions</a></b><br /><br />A triangle that does not contain a right angle is called an oblique triangle. One that does is a right triangle. <br />There are two types of oblique triangles, those with all the internal angles smaller than 90°, and those with one angle larger than 90°. <br />The obtuse triangle contains the larger than 90° angle, known as an obtuse angle. The acute triangle is composed of three acute angles, the same as saying that all three of its angles are smaller than 90°. <br />A right triangle (or right-angled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. Right triangles conform to the Pythagorean theorem: the sum of the squares of the two legs is equal to the square of the hypotenuse; i.e., a2 + b2 = c2, where a and b are the legs and c is the hypotenuse<br /><br /></span> </div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-21277778602422550702011-03-07T20:46:00.000-08:002011-10-07T06:47:20.963-07:00Set of mathematical for Junior High School<div align="justify"><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-Wuo8rEHjJMA/TXW0MI55cTI/AAAAAAAAASw/Fn-N0JoX9Aw/s1600/matematika-himpunan.png" imageanchor="1" style="clear:left; float:left;margin-right:1em; margin-bottom:1em"><img border="0" height="250" width="320" src="http://1.bp.blogspot.com/-Wuo8rEHjJMA/TXW0MI55cTI/AAAAAAAAASw/Fn-N0JoX9Aw/s320/matematika-himpunan.png" /></a></div>A set is a collection of distinct objects, considered as an object in its own right.

There are two common types of operations: unary and binary. Unary operations involve only one value, such as negation and trigonometric functions. Binary operations, on the other hand, take two values, and include addition, subtraction, multiplication, division, and exponentiation.<br /><span class="fullpost"><br /><br /><b><a href="http://maximizes.blogspot.com/2011/03/mathematics-rank-and-square-root.html" target="_blank">Download Theory of Mathematics UN SD according to grid UN 2010/2011</a></b><br /><b><a href="http://maximizes.blogspot.com/2011/03/questions-of-mathematics-rank-and.html" target="_blank">Download the sample of Questions</a></b><br /><br />Operations can involve mathematical objects other than numbers. The logical values true and false can be combined using logic operations, such as and, or, and not. Vectors can be added and subtracted. Rotations can be combined using the function composition operation, performing the first rotation and then the second. Operations on sets include the binary operations union and intersection and the unary operation of complementation.

The major difference between algebra and arithmetic is the inclusion of variables. While in arithmetic only numbers and their arithmetical operations (such as +, −, ×, ÷) occur, in algebra, one also uses symbols such as x and y, or a and b to denote variables.<span class="fullpost"><br /><br /><br /><br /><br /><b><a href="http://maximizes.blogspot.com/2011/03/mathematics-number-of-factors-fpb.html" target="_blank">Download Theory of Mathematics UN SD according to grid UN 2010/2011</a></b><br /><b><a href="http://maximizes.blogspot.com/2011/03/questions-of-mathematics-number-of.html" target="_blank">Download the sample of Questions</a></b><br /><br />The purpose of using variables, symbols that denote numbers, is to allow the making of generalizations in mathematics. <br />It allows reference to numbers which are not known.

Operations can have fewer or more than two inputs.<br />An operation is like an operator, but the point of view is different. For instance, one often speaks of "the operation of addition" or "addition operation" when focusing on the operands and result, but one says "addition operator" (rarely "operator of addition") when focusing on the process, or from the more abstract viewpoint, the function +: S×S → S.<span class="fullpost"><br /><br /><br /><b><a href="http://maximizes.blogspot.com/2011/03/mathematics-integer.html" target="_blank">Download Theory of Mathematics UN SD according to grid UN 2010/2011</a></b><br /><b><a href="http://maximizes.blogspot.com/2011/03/questions-of-mathematics-integer.html" target="_blank">Download the sample of Questions</a></b><br /><br />An operation ω is a function of the form ω : V → Y, where V ⊂ X1 × … × Xk. The sets Xk are called the domains of the operation, the set Y is called the codomain of the operation, and the fixed non-negative integer k (the number of arguments) is called the type or arity of the operation. Thus a unary operation has arity one, and a binary operation has arity two. An operation of arity zero, called a nullary operation, is simply an element of the codomain Y. An operation of arity k is called a k-ary operation. Thus a k-ary operation is a (k+1)-ary relation that is functional on its first k domains.<br /><br /></span> </div>sony vickyanoreply@blogger.com0tag:blogger.com,1999:blog-715455830290139585.post-79906640149337068702011-03-06T10:52:00.000-08:002011-10-07T06:47:20.964-07:00Mathematics for elementary school Part 3<div align="justify">Operations may not be defined for every possible value. For example, in the real numbers one cannot divide by zero or take square roots of negative numbers. The values for which an operation is defined from a set called its domain. The set which contains the values produced is called the codomain, but the set of actual values attained by the operation is its range. For example, in the real numbers, the squaring operation only produces nonnegative numbers; the codomain is the set of real numbers but the range is the nonnegative numbers.<br />Operations can involve dissimilar objects. <br /><span class="fullpost"><br /><br /><b><a href="http://maximizes.blogspot.com/2011/03/mathematics-operations-fractions.html" target="_blank">Download Theory of Mathematics UN SD according to grid UN 2010/2011</a></b><br /><b><a href="http://maximizes.blogspot.com/2011/03/questions-of-mathematics-operations.html" target="_blank">Download the sample of Questions</a></b><br /><br />A vector can be multiplied by a scalar to form another vector.
