拉格朗日中值定理的应用

Application of Lagrange mean value theorem

研究了如何应用拉格朗日中值定理求极限、证明不等式、恒等式、判定函数的单调性以及确定方程的根,通过给出相关例子加以说明。

This paper studies the application of Lagrange mean value theorem, while solving the limit, proves the inequality, identities, detects monotonous nature of function and identifies roots of equation in it, and gives the relevant examples to explain.
