Одна из самых популярных математических программ в Германии для учащихся средних школ и учителей. Программа помогает в решении большинства задач: алгебры, геометрии, линейной алгебры и аналитической геометрии, стохастики (вероятности и статистики)."Math-Assist" means Mathematical Assistant and that's exactly what this program is designed to be. It's for secondary level or high school students and teachers and anybody else who has anything to do with mathematics.Math-Assist helps in solving most of the tasks of :Algebra Prime numbers The prime numbers or twin primes between two natural numbers a and b are calculated. Prime Factorization The prime fatorization of a natural number n 1014 is calculated. G.C.F. and L.C.M. The greatest common factor (GCD) the least commun multiple (LCM) and the sets of divisors of up to 10 numbers are calculated. Decimals to Fractions Periodical decimals will be transformed to fractions. Fractions to Decimals Fractions are transformed in periodical decimals and also the period and its length are determined. Binomials of n-th Degree The binomial ( a·x + b·y )n with 1 n 500 is calculated. Equations of 4-th Degree The solutions of a·x4 + b·x3 + c·x2 + d·x + e = 0 is calculated . Diophantine Equations The integer solutions of a·x + b·y + c = 0 with a, b, c integer are calculated. Pythagorean Triples The pythagorean triples between two bounds are calculated. Calculators Calculation in place value systems Calculation with fractions Calculation with complex numbersGeometry Right-angled Triangles Given two of the elements of a right-angled triangle the others are calculated. Triangles by three Elements or Points Given three elements or three points of any triangle the program calculates the sides, altitudes, medians, bisectrices, circumcircle, incircle, perimeter and area. Regular Polygones Given one of the following elements of a polygone with n vertices, the others are calculated. Side, Circumcircle, Incircle, Perimeter and Area. Arbitrary Polygones Area, perimeter and centroid of a polygone are calculated Mappings of Polygones A polygone can be mapped by a translation, axial symmetry, point symmetry, rotation, homothetic stretching, shear transformation or any combination of them. Circles and its Parts Given two elements of a circular section, radius, angle, arc, chord, section, segment, area, perimeter, distance between chord and arc and the arrow height are calculated. Coordinate Systems Transformation between cartesian coordinates, polar coordinates and cylindrical coordinates. Platonic Bodies Calculates all elements of a Tetrahedron, a Hexahedron, a Octahedron, a Dodekahedron or a Icosahedron Other Bodies Calculates all elements of a Regular Prism, a Right Circular Cylinder, a Regular Pyramid, a Right Circular Cone or a Sphere. Line through two Points Two points determine a straight line. Its equation will be formed and its position to the co-ordinate planes are analysed. Plane through three Points Three non-kollinear points determine a plane. The equation of this plane is formed as Point-slope-form and as Equation in coordinates. The distance from origin and the Trace Points is calculated. Sphere through four Points Four non-coplanar points determine a sphere. The equation of this sphere is formed. Intersections in the Plane The intersections between two lines, a line and a circle and between two circles are calculated. Intersections in the Space The intersections between two lines, a line and plane, two planes, a line and a sphere, a plane and a sphere and between two spheres are calculated. Distances The distance between two points, a point and line, a point and a plane, between two lines, a line and a plane and between two planes are calculated.Analysis Division of Polynomials The product and quotient of two polynoms will be calculated. Function Plotter There are three plotters. One for up to five explizit functions, one for segmentwise defined functions and one for functions in parametric representation. Curve Discussion Curve discussion of an arbitrary function. The derivations, zeros, extrema and points of inflection are determined. Newton-Iteration Approximation of the zeros of a function f(x) by Newton's method with a first guess x0. Series Expansion Plotter for functions given as a series over f(x,k). You may develop the function with different parameter ranges and different y-offset. Integral Calculus The definite integral over f1-f2 from a to b is calculated as well as the oriented and absolut content under the curve, the twisting moments, the bodies of revolution and the centroid. Area Functions Plotter for an area function f(x,y), which may contain a subterm u(x,y).Stochastics Statistics Mean, median, standard deviation and variance of a sample and the corresponding histogram are calculated. Regression The regression curve to fit a sample of points is calculated. Supported are proportional regression, linear regression, geometrical regression, exponential regression, logarithmic regression and polynom regression Combinatorial Analysis The number of arrangements and combinations of k out of n elements, with or without repetitions are calculated. Binomial Distribution For a b(k;n;p) distributed random variable X with fixed n and p you receive a histogram of the probabilities P( X = k ), a table of their values from kmin to kmax and the probability P(kmin≤X≤kmax). Hypergeometric Distribution For a h(k,n,m,r) distributed random variable X with fixed n, m and r you receive a histogram of the probabilities P( X = k ), a table of their values from kmin to kmax and the probability P(kmin≤X≤kmax). Normal Distribution For a normal distributed random variable X with given mean μ and variance σ you receive the density function and the distribution function.Linear Algebra Systems of Linear Equations The solution of a system of linear equations will be calculated.
