soooo over the summer I taught myself a pretty wide range of alg/trig based physics, all of the topics on the AP exam plus a little bit of relativity and other Einstein things. This year I'm taking an AP physics class, that covers the aforementioned topics, but nothing on Calc/AP physics BC.

So I want to teach myself calculus based physics. How much Calculus do you really need to know for physics? For example I know you need relatively little algebra and trig for the physics I've already studied. Basically what I'm asking is, should I go all in and buy a calculus textbook, or will a calc-based physics book contain all of the calc I need?

For point of reference, I know nothing about Calculus, and I'm only interested in learning what I'll need to use for physics.
