拉格朗日中值定理辅助函数构造法的证明

Demonstration about the Structure Law of Auxiliary Function by the Lagrange Theorem Mean

文章给出了用四则运算以及两个函数的复合运算构造辅助函数来证明拉格朗日中值定理的方法,这也是用基本初等函数构造全部初等函数的方法,因而比较圆满地解决了辅助函数构造问题。

Proving Lagrange theorem mean through the introduction of auxiliary iunctlon, this article puts forword the methods of building auxiliary function by the mathematical operations and two functions compound operation ; this is a method building all elementary function by the basic elementary function , which is a way to solve the problem of the auxiliary function building.
