Lagrange中值定理证明的几点注记

Several Remarks on Proving the Mean Valve Theorem of Lagrange

证明Lagrange中值定理的关键是构造一个满足Rolle定理条件的辅助函数,用代数和几何的知识构造出几个辅助函数,从而注明了构造辅助函数的思想方法.

Constructing auxiliary function to meet the condition of Rolle Theorem is very important in proving the mean valve theorem of Lagrange.This paper gives several methods and thoughts of constructing auxiliary functions.
