Summary of Integrals Involving Exponential and Logarithmic Functions

Essential Concepts

Exponential and logarithmic functions arise in many real-world applications, especially those involving growth and decay.
Substitution is often used to evaluate integrals involving exponential functions or logarithms.

Key Equations

Integrals of Exponential Functions
$\displaystyle\int {e}^{x}dx={e}^{x}+C$
$\displaystyle\int {a}^{x}dx=\frac{{a}^{x}}{\text{ln}a}+C$
Integration Formulas Involving Logarithmic Functions
$\displaystyle\int {x}^{-1}dx=\text{ln}|x|+C$
$\displaystyle\int \text{ln}xdx=x\text{ln}x-x+C=x(\text{ln}x-1)+C$
$\displaystyle\int {\text{log}}_{a}xdx=\frac{x}{\text{ln}a}(\text{ln}x-1)+C$
