The Great Equation Graph is a mathematical tool designed to allow representation of abstract mathematical situations and graphing of equations.
tgeg 0.0.1 (DOS)
Perhaps a bit outdated, the original DOS version of tgeg is still very cool. Notice the cool-looking conics sections (especially x^2 + xy - y^2 = 0, in purple) and the excellent sine wave graph. Too bad the user interface is not the least bit portable. Oh well.
tgeg 0.1.0 (Windows/Linux)
A bold attempt at creating a Windows/Linux interface, this version of tgeg uses a new code base and acts somewhat like a command-line calculator. However, since this was my first venture into windowed programming, it doesn't do very much.
