留数定理在实积分中的应用研究

Research on the Residue Theorem in the Application of the Real Integration

留数定理是复变函数中最重要的定理之—,通过应用留数定理将几种实函数积分转化为复函数积分,达到了化难为易,化繁为简的效果,并举例加以说明。

The residue theorem is the most important theorem of complex functions.In this paper, it applies theresidue theorem to several real function integral into copmplex function integral to achieve the effect of making hardthings simple with some examples to illustrate.
