用函数模型证明不等式

Prove the Inequality with the Function Model

不等式的证明很具技巧性,本文利用构造函数模型的方法,将不等式的证明转化为函数模型,使得解题简洁明了.

The identification of the inequality has skill nature very much, this text utilizes the method to construct function model, turn function model into identification of inequality, it makes a problem succinctly and clearly to solve.
