Basic Integrals

· Constant factor Rule

$\int cxdx=c\int xdx$

· Sum Rule of Integration

$\int\left(a+b\right)dx=\int adx+\int bdx$

Trigonometric Integrals

$\int\sec\left(x\right)\tan\left(x\right)^2dx=\int\sec\left(x\right)^3dx-\int\sec\left(x\right)dx$

$\int\sec\left(x\right)dx=\ln\left|\sec\left(x\right)+\tan\left(x\right)\right|+C$

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

Basic Derivatives

· Derivative of the linear function

$\frac{d}{dx}\left(x\right)=1$

Derivatives of trigonometric functions

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