one day i was sort of "challenged" to make a cool graphing
calculator. since i really don't have much of a life, i made one.
the hardest part was making the equation parser/interpreter... the graphics were surprisingly easy (thank you, opengl.)
for now, i think it supports abs, sin, cos, tan, asin, acos, atan, log, ln, +, -, *, /, ^ and maybe some others i'm forgetting.
anyways, check it out and email me with any neat equations you find. if it looks funny, try downloading the opengl dlls i provide, they might be more up to date than yours (just unzip into the same directory.) if you just can't get it to work, tell me what's wrong and i'll see if i can help.
