关于残数定理的一些应用

The application of residue theorem

残数定理是复变函数论中的基本理论,它有着十分重要的应用。本文阐述了残数定理在计算定积分,广义积分,级数求和等方面的应用。

The residue theorem is the basic theorem in the Theory of complex Variable Function.Its application is very important.This pepper expounds its application in calculation of real integrals and the sum of some series,and in proving some identical relations algebra.
