Evaluating Real Integrals With Cauchy's Residue Theorem - Complex Analysis By A Physicist

In this video we go over what is one of the most important and useful applications of Cauchy's Residue Theorem, evaluating real integrals with Residue Theorem. This may seem a bit confusing. How can we evaluate a real integral with a complex analysis theorem? The answer is very interesting and opens up the ability to evaluate many different kinds of integrals via analytic means.
