What do you all think:

I want to start using my laptop to take notes in my math class. We just finished what we are doing with calculus and we are going into statistics. I am thinking that I will get a small pad and a frogpad to take notes, that way I can draw graphs and draw graphs and equations in, because graphs and equations are way too hard otherwise. Has anyone tried something like this. Does anyone have a better idea? I am trying to keep the budget down. I like the frogpad for other uses, so that will more than likely stay. I mostly need help with a way to write in equations and graphs, without all the ink and paper, and ideally without the pad. Thanks a bunch.
