How to evaluate some real integrals by using contour integration? Need to write like a short section of a book, and cite sources used (include the page number of the source you used, which specific example/exercise on what page you have used, and so on). Need to include some examples. The sources you can use: the textbook , no other materials are allowed. Do not exceed four pages. the book is Complex Variables with applications: A. David Wunsch

the pdf for the book is on this website:
