Lagrange定理辅助函数的构造

Lagrange theorem auxiliary function is constructed

文章主要探讨微积分学中辅助函数的构造,给出以Rolle定理为基础,用不同的构造辅助函数的方法来证明Lagrange定理,这里仅从分析法、尝试法、几何法来进行讲解说明。

This paper discusses the structure of the auxiliary function calculus, given the Rolle theorem, Lagrange theorems different construct the auxiliary function method to prove, and here only from the analysis, try the method, geometric method to explain the instructions.
