函数是贯穿中学数学的一条主线,不等式是中学数学的重要内容之一.对于一些不等式的证明问题,通过类比、联想、转化,合理地构造函数模型,利用函数的单调性可以得到巧妙的解决.本文结合具体实例谈一谈怎样构造函数模型来证明不等式问题.
Function is one of the main lines of mathematics in the middle school, which is one of the important contents of mathematics in middle school.For the proof of some inequalities, the function model can be reasonably constructed through analogy, association and transformation, and the monotonicity of the function can be cleverly solved. This article with specific examples talk about how to construct a function model to prove inequality problems.
