高等数学中辅助函数的构造方法

How to Create a Subfunction in Advanced Mathematics

根据高等数学各部分知识间的内在联系 ,构造出最恰当的辅助函数 ,本文实例就此问题进行归纳 ,总结出利用函数的性态、中值定理。

According to the internal relations among various parts in advanced mathematics, the most appropriate subfunction can be created. This paper makes an analysis on this issue with examples and provides a summary for creating methods: making use of the character of function, medium number theorem, solution of differential equation and integrative analysis.
