Hi! I was wondering if a graphing calculator (like the HP 50g, which really "turns me on") is really necessary for studying physics. I guess you're not counting much in these courses, you're just going to operate on a's and x's while using a simple calculator just to get the exact result at the end. Do I need to have such a calculator for my physics studies? Will it help me, will it improve my studies or would it just make everything harder? What do you think?
