Rewriting Before Integrating

The video tutorial explains various integration rules, including the constant rule, constant multiple rule, power rule, and sum and difference rule. It demonstrates how to integrate complex functions by rewriting them into simpler forms. Two examples are provided: one involving a square root function and another involving trigonometric and exponential functions. The tutorial emphasizes the importance of rewriting functions to apply known integration rules effectively.

Describe the constant multiple rule and how it applies to integration.

What is the power rule for integration?
