不等式证明是我们学习高中数学第二册上不等式一章必须面对的重要内容,与很多知识点都有着密切的联系,因此,它也是本章的难点之一。不等式证明除了课本介绍的比较法(比差,比商)、综合法、分析法和均值不等式法外,为了便于同学们梳理不等式的证明方法,针对具体问题具体分析,达到有的放矢,现归纳整理如下。 Inequalities prove that we have to learn an important part of the chapter of inequality in the second book of high school mathematics, and are closely linked with many knowledge points. Therefore, it is also one of the difficulties in this chapter. Inequality Proof In addition to textbook comparison method (ratio difference, than quotient), synthesis method, analysis method and mean inequality method, in order to facilitate students to sort out the inequality of proof methods, specific analysis of specific issues, to achieve targeted, are summarized as follows .
