u-Substitution

The video tutorial covers the concept of U substitution, a technique used in integration that is essentially the reverse of the chain rule in differentiation. It provides a step-by-step explanation of how to apply U substitution to solve integrals involving composite functions. The tutorial includes three examples: integrating functions with square roots, cubes, and exponential terms. Each example demonstrates how to identify the inner and outer functions, substitute variables, and apply integration rules to find the antiderivative. The video emphasizes the importance of substituting back to the original variable to complete the solution.
