AP Calculus AB/BC Formula Sheet

Every limit, derivative, and integral formula you need for the AP Calculus exam, verified against the latest College Board CED.

LIMITS & CONTINUITY

\lim_{x \to c} f(x) = LDefinition of a limit
f(c) \text{ is defined, } \lim_{x \to c} f(x) \text{ exists, } \lim_{x \to c} f(x) = f(c)Definition of continuity
\lim_{x \to 0} \frac{\sin x}{x} = 1Special trigonometric limit

DERIVATIVES (RULES)

\frac{d}{dx}[f(g(x))] = f'(g(x))g'(x)Chain Rule
\frac{d}{dx}[uv] = uv' + vu'Product Rule
\frac{d}{dx}[\frac{u}{v}] = \frac{vu' - uv'}{v^2}Quotient Rule

INTEGRALS

\int f(g(x))g'(x) dx = F(g(x)) + Cu-Substitution
\int u dv = uv - \int v duIntegration by Parts
\int_a^b f(x) dx = F(b) - F(a)FTC Part 2
