摘要
辅助函数在高等数学中有着广泛的应用,但是要在具体应用中恰到好处引入一个辅助函数并不是一件容易的事,特别对于初学者来说更是困难,本文从两个定理的证明人手定性的分析了在解题时构造辅助函数应该考虑的问题以及构造方式。
Aided function has a wide use in the higher mathematics, but it is not an easy thing to lead an aided function into the practical application, especially for the beginners. This paper analyzes the questions that should be considered in constructing an aided function and the construction pattern from the verification of two theorems.
