Integration Techniques and Concepts

This video tutorial demonstrates integration by substitution, focusing on a composite function. The process involves identifying the inner function, finding its differential, and substituting it into the integral. The tutorial simplifies the integral using algebraic manipulation and applies the power rule to find the anti-derivative. The final result is expressed in a simplified form, illustrating the effectiveness of the substitution method.

What is the first step in integration by substitution?
