I've struggled through Calc 1 without a graphing calculator. Next term (after the new year) I start Calc 2 (Integrals). The professor says that we don't need a graphing calculator, but he highly recommends that we have one. Anyways, I'm too cheap to purchase one, especially since I bought a new laptop that I've barely used. So i figured that there has to be some software program that will let me do all the functions of the latest & greatest graphing calculator. Anyone out there have any recommendations?
