摘要
幂级数和函数问题是数学分析课程中的重要内容,利用和函数这一数学工具可以有效解决数学中的很多问题.介绍了幂级数和函数的性质以及求和函数的方法,对幂级数和函数在求极限、数项级数的和、不等式的证明、积分计算、近似计算中的应用展开了讨论.
The sum functions of power series is an important part in the mathematics analysis course,and the use of sum functions as a mathematical tool can effectively deal with many problems in mathematics.This paper introduces the properties and methods of sum function of power series,and discusses the application of sum function of power series in limit,sum of number series,proof of inequality,integral calculation and approximate calculation.
