Research on Complex Power Series Problems in Function Theory
Abstract: This paper mainly introduces the power series convergence, convergence radius and analysis. The second is the Taylor expansion series includes expansions for the function pision of the power series, and a special method of expression and function in power series convergence on the circumference. Finally introduce the power series in the application of the function of complex variable. Including the application in power series in the summation of trigonometric functions.
Keywords:The theory of complex functions; Power series; Convergence; Radius of convergence; Taylor expansion
