Corner is a program for calculating odd corners on items to be made from sheet materials like aluminium, steel, or glass. It could be the corners of aluminium or steel facades - or perhaps strangely-shaped fishtanks ;-) If you are in that line of work or a bit interested in geometry, Corner will be very easy to use as you will recognize the scenario - if not Corner will be useless to you!
Performs several kinds of computations involving complex numbers, finds the prime factors of positive integers, converts numbers from base 10 to any other base in the range 2 £ BASE £ 36 and vice versa. 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. 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; 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). Grapher generates graphs for explicit equations in 2D, 3D, and any higher spatial dimension (Hyperspace). Multiple coordinate systems are supported such as Cylindrical, Spherical, and Polar. Create graphs that can be viewed with anaglyph glasses or exported to *.DXF (AutoDesk), *.BMP, or *.TXT file formats. Requirements: OpenGL, Windows 9x. May work with Win2000, WinME, and seems to work with WinXP (not fully tested) Another random-number-file generator! Allows several different algorithms to be used, and a couple of distributions. Also allows some analysis and visualisation of the resultant file. Linear algebra functions in "C" language. a)addm, subm, multm, powm, smultm, transpose, trace, det, minor, mminor, cofactor, mcofactor, adjoint, inverse, inverse(gaussjordan), gauss, gaussjordan. b) With several applications. Now you can practice your multiplication tables with animated graphics, sounds, music, and an ever changing memory game. It has optional sounds to indicate right and wrong answers as well as optional background music. The current score and an all-time high score is kept as you answer arithmetic questions of increasing difficulty. You can also adjust the window position and the colors or have MathQuiz adjust them for you at random to keep the game fresh for students. The program is organized into several short and easy to learn lessons with several different levels of increasing difficulty as you go, and with good reinforcement of correct perfomance. Dynamics Solver is a powerful tool to study differential equations, (continuous and discrete) nonlinear dynamical systems, deterministic chaos, mechanics, etc. For instance, You can draw phase space portraits (including an optional direction field), Poincaré maps, Liapunov exponents, histograms, bifurcation diagrams, attraction basins, etc. The results can be watched (in perspective or not) from any direction and particular subspaces can be analyzed. It is also able to draw complex mathematical figures, including many fractals. This program will convert Decimal, Hexadecimal or Binary numbers and the results can be transferred to a results table ready for printing or saving into a .txt file. There is a full Help file with this program. KarnaughMap is a freeware boolean algebra program. It is an interactive Boolean Algebra program extremely easy to use. You enter the specification through the truth table. The moment you click on a cell, the corresponding cell on the Karnaugh map also gets updated. Alternatively, you may enter data into the Karnaugh map directly. If you do so, the truth table will be updated real-time to reflect the Karnaugh map.

PSI plans to augment this free software release in future, with other topical folders. Flash Calc is the flash mental calculation software - The flash mental calculation is the supreme mental calculation by the abacus. Let's challenge the flash mental calculation with this program. Argand displays the real and imaginary parts of complex functions, or conformal transformations. Built-in functions include sine, cosine, tan, sinh, cosh, exp, and Log, and these can be combined to produce a wide range of expressions such as tan(z-2*i) - sin(z*z). These expressions can be displayed in terms of their real and imaginary parts, or used to tranform shapes from the z to the w plane. Draws a graph from an algebraic formula entered by you, functions such as sine, cosine, tan, log, log natural and powers can be used. The x and y range displayed on the axis can be altered to zoom in and zoom out on the graph. Grid lines and value labels are displayed on the graph for easy reading. Graphs can also be printed on any standard printer in landscape and portrait mode. Equation Grapher has the ability to create 2D equation graphs, Cartesian and polar coordinate systems, the equation can be in the form of y=f(x) or x=f1(u), y=f2(u).
