求解幂级数半径的五种有效方法

Five Methods of Solving the Power Series's Convergence Radius

关于幂级数半径的求解方法,《高等数学》课程教学中一般只给出两种,即论文中的"方法一"和"方法三",文中给出另外的三种有效方法,上述五种基本满足各类材料中出现的求解幂级数半径习题的需要.

There are only two methods in many Mathematics References about the solution of the power series＇s convergence radius. This article introduces five effective methods, which can basically satisfy the requirement of the solution of the power series＇ convergence radius.
