I think calculus is the coolest thing ever. My math teacher gave me a calculus book for the summer and I've been reading it quite a bit, but he says I cannot take calculus next year because I do not have enough knowledge to be able to do it.

Personally, i think that is a load of horse $$$$. But I wanted to know what you guys (people that have or are actually taking calculus, not losers who think they know what calculus takes when they don't know what a radian is) think it really takes for pre requisites to calculus.

My math teacher said having a solid understanding of trig identities is key, which is believable, but he didn't say what else I would have to get into, and honestly I'm good at trig and math in general. PooP

EDIT: yes, I'm a geek, well established
