I'd say you still need the calc skills so you'll know what you're doing: sympy helps with demos, explorations, and tedious calculations, but not with the theory

I'd say you still need the calc skills so you'll know what you're doing: sympy helps with demos, explorations, and tedious calculations, but not with the theory. For example, here's a little demo that shows that integration is the "undo" operation of differentiation http://bit.ly/1dDD4dc http://bit.ly/1dDD4dc but that won't make you really understand the fundamental theorem of calculus[1]. ____________________ [1] http://en.wikipedia.org/wiki/Fundamental_theorem_of_calculus#Physical_intuition http://en.wikipedia.org/wiki/Fundamental_theorem_of_calculus...
