关于应用残数定理证明代数恒等式问题的探讨

The Research on Bearing out Identical Relations of Algebra by Residue Theorem

函数在孤立奇点的残数 ,函数在无穷远点的残数。利用残数及残数定理可以证明高等代数中的一些恒等式 。

Some identical relations in adanced algebra can be borne out with the help of the residue of a function at the isolated singular point and residue of a function at the point at infinite, and the residue theorem, as well as the Lagrange interpolation formula at the same time.
