摘要
在无穷级数中,求常数项级数的和是难点.而计算常数项级数和的方法有多种,该文对构造幂级数的和函数,利用幂级数的和函数的分析运算性质求常数项级数的和进行了研究。针对一道求常数项级数和的具体问题进行了探讨,给出了4种构造幂级数的方法,并对每种方法的注意事项、使用技巧进行了简单的分析和说明。
in inf inite series,it is diff icult to f ind the sum of series of constant terms.There are many ways to f ind the sum of series of constant terms.in this paper,we study how to construct the sum function of power series and f ind the sum of the series of constant terms by using the analytic property of the sum function of power series.This paper discusses a specif ic problem of of f inding the sum of series of constant terms,four methods of constructing power series are given,furthermore,the limitations,techniques for each method are analyzed and illustrated brief ly.
