## Basic Integrals

· Constant factor Rule
$\int cxdx=c\int xdx$
· Sum Rule for Integration
$\int\left(a+b+...\right)dx=\int adx+\int bdx+...$

## Derivatives of trigonometric functions

$\frac{d}{dx}\left(\sec\left(x\right)\right)=\frac{d}{dx}\left(x\right)\sec\left(x\right)\tan\left(x\right)$

## Basic Derivatives

· Derivative of the linear function
$\frac{d}{dx}\left(x\right)=1$

## Trigonometric Integrals

$\int\sec\left(x\right)^2dx=\tan\left(x\right)+C$
$\int\sec\left(x\right)\tan\left(x\right)^2dx=\int\sec\left(x\right)^3dx-\int\sec\left(x\right)dx$
$\int\sec\left(x\right)dx=\ln\left(\sec\left(x\right)+\tan\left(x\right)\right)+C$
$\int\sec\left(x\right)^ndx=\frac{\sin\left(x\right)\sec\left(x\right)^{\left(n-1\right)}}{n-1}+\frac{n-2}{n-1}\int\sec\left(x\right)^{\left(n-2\right)}dx$

## Integration Techniques

· Integration by Parts
$\int udv=uv - \int vdu$
