Estimating Definite Integrals Using Power Series

The video tutorial demonstrates how to estimate the value of a definite integral using both exact and power series methods. Part A involves finding the exact value using arctangent, while Part B uses a power series approach to approximate the integral. The tutorial then compares the results from both methods, showing their equivalence, and uses the series to approximate pi. Finally, it discusses error estimation using the alternating series method.
