Discussion on the computational methods of complex integration
ABSTRACT
Complex integration entails Complex integration」n the analysis of the complex function theory,Complex integration is an important tool for analytic important properties of analytic functions must use the complex function points to prove that the Cauchy integral theorem in a key position in the calculation of the complex integral theory,Therefore,Complex integral calculation is particularly important ..The integral in the complex variable function is not only an important tool for the study of analytic functions,Also the basis for its successor course integral transforms , integral calculation of the complex function method summary and discussion is very integral formula , Cauchy order derivative formula and residue theorem has played a significant role in the calculation of complex residue theorem can not only be used to calculate the complex integration,A nd can be used to calculate the real integral,It organic combination of real integral and complex integration of knowledge ..
This paper discusses the intrinsic link between the stay theorem Complex integration,And illustrates the residue theorem, the close relationship between the Cauchy integral theorem, Cauchy integral formula and the Cauchy higher derivative article will use the basic principles of Complex integration,Th
