Conquering AP Calculus with the Ultimate Formula Guide
As an AP Calculus student, navigating the vast ocean of formulas can be daunting. But fear not, for this comprehensive formula sheet serves as your anchor, providing a lifeline to conquer the complexities of calculus.
Key Concepts and Formulas
**Limits and Continuity**
-
$\lim\limits_{x\to a} f(x) = L$ if for every $\epsilon > 0$, there exists a $\delta > 0$ such that if $0 < |x - a| < \delta$, then $|f(x) - L| < \epsilon$.
-
$f$ is continuous at $a$ if $\lim\limits_{x\to a} f(x) = f(a)$.
**Differentiation**
-
$\frac{d}{dx}(x^n) = nx^{n-1}$
-
$\frac{d}{dx}(\sin x) = \cos x$
-
$\frac{d}{dx}(\cos x) = -\sin x$
-
$\frac{d}{dx}(\tan x) = \sec^2 x$
-
$\frac{d}{dx}(\sec x) = \sec x\tan x$
-
$\frac{d}{dx}(\csc x) = -\csc x\cot x$
-
$\frac{d}{dx}(\cot x) = -\csc^2 x$
-
$(fg)'(x) = f'(x)g(x) + f(x)g'(x)$ (Product Rule)

$\int \sec x dx = \ln |\sec x + \tan x| + C$
-
$\int \csc x dx = -\ln |\csc x + \cot x| + C$
-
$\int \cot x dx = \ln |\sin x| + C$
-
$\int e^x dx = e^x + C$
-
$\int \frac{1}{x} dx = \ln |x| + C$
