Applying Residue Theorem to Compute Real Definite Integral
Nanru Dai, Yunxing Zhang · Journal of Physics Conference Series · 2021
Abstract The Residue Theorem is one of the fundamental theorems in complex analysis. It can be used to integrate some types of real functions that are difficult, or even unable, to be expressed in terms of fundamental functions. This paper reevaluates the application of the Residue Theorem in the real integration of one type of function that decay fast.
