MathCast is an equation editor, an application that allows you to input mathematical equations. These equations can be used in written documents, webpages, and even databases. They could be rendered graphically to the screen, to picture files, or to MathML - today’s leading standard language for describing mathematics.
MathCast can be used freely by anyone: students can create equation sheets to help them in their studies, educators can write handouts or study guides, webmasters can add mathematics to their website, and the list goes on and on.
Performs several kinds of computations involving complex numbers (In addition to the elementary operations of addition, subtraction, multiplication and division of two complex numbers, it also finds exponentials, logarithms, nth power, nth roots, and polar forms), finds the prime factors of positive integers (This program uses a table of primes), converts numbers from base 10 to any other base in the range 2 £ BASE £ 36 and vice versa, solves problems involving circles (It finds two given the other two of: radius, arc, chord, central angle. It also finds the areas of the sector and the segment), solves triangles, that is, given 3 of its elements, the remaining elements are calculated (The given elements may be the three sides (SSS), two sides and an angle (SSA or SAS), or two angles and a side (ASA or SAA). The area of the triangle is also calculated).
This is a Windows application for visualising complex functions.
It is named after the Argand diagram, upon which complex numbers can be plotted as points, with their real parts along the x axis and imaginary parts on the y axis.
Argand can be used in two main modes :
To display the real and imaginary parts of a complex function. One window shows the real part, as a vertical distance above the z plane. Another window shows the imaginary part above the z plane.
Alternatively it can show a transformation. One window shows a shape (rectangle, line, ellipse, grids) in the z plane, while the other shows the transformation of those points by the function onto the w plane ( where w = f(z) ). The integral of the function over the path is also shown. These conformal transformations are heavily used in physics and engineering.
Calendar Magic is an easy-to-use freeware Windows 95, 98, Me, XP, 32-bit Vista based program that is entertaining, informative, educational, and of equal applicability in the home and in the office.
