摘要
文章介绍了常用的微分中值定理:罗尔定理、拉格朗日中值定理、柯西中值定理,论述了利用这三种定理在解题过程中辅助函数构造的常用方法:原函数法、常数K值法、利用函数增量构造辅助函数。
This paper introduces the commonly used differential intermediate value theorem： Rolle theorem, Lagrange mean-value theorem, Cauchy Mean-Value Theorem, and discusses the use of this theorem in the problem solving process of three kinds of auxiliary functions constructed common methods： the original function method , constant-K-value method, using the function Incremental Construction of auxiliary functions.
