AP Calculus BC - Stuff You Must Know

This includes a ton of stuff you must remember for the AP Test. It includes equations, theories, rules, derivatives, integrals, and more. I only recommend using these as flashcards or multiple choice only.

Intermediate Value Theorem

If the function f(x) is continuous on \[a,b\], then f(x) achieves every value between f(a) and f(b) in the open interval (a,b).

Mean Value Theorem

If the function f(x) continuous on \[a,b\], and the first derivative exists on the interval (a,b), then there is at least one number x = c in (a,b) such that f’(c) = \[ f(b)-f(a) \] / (b-a).

Rolle’s Theorem

Same as mean value theorem but if f(a) = f(b), then there is at least one number x = c in (a,b) such that f’(c) = 0.
