Integration round the unit circle|Method of contour integration|Part 1|Theta Classes

In this video we will learn to solve Definite integrals by the method of contour integration.Under the application of Cauchy residue theorem we will solve the integrals in which we integrate round the unit circle using the method of contour integration.In order to solve integrals of the particular form as mentioned in the video we will first make some substitution and then we will solve them by the help of Cauchy residue theorem.While solving we will also see the use of residue. If anyone has any doubt regarding this problem solving please do write it in the comment section. Keep connected with the Theta Classes to study various topics of higher mathematics.
