I wrote this program for every lazy person that doesn't feel like doing their geometry work themselves. It solves for area, volume, surface area for most major shapes and displays their formulas Solves for distance equation, midpoint, slope and more I think that every part of the program works and that every answer should be right should work on both ti 83 and ti 83+ (made for ti83+) if you have any questions on basic programming or about this program e-mail me at khameleon69@hotmail.com
