不等式是中学数学的基础和重要部分,是进步学习高等数学的基础和重要工具,也是每年高考必考的热点内容.不等式的解、证,是不等式问题中最重要的一种题型,是应用化归思想完成从已知到待证结论的一个转化过程,而且能更有效地测试逻辑推理能力、代数推理能力以及运用相关知识和方法去分析问题和解决问题的能力,解证不等式的方法很多.本文介绍用构造法解证不等式,供参考.
Inequality is the basic and important part of middle school mathematics. It is the basic and important tool for advanced mathematics, and it is also a hot topic for college entrance exams. The solution and proof of inequalities is the most important question in inequality problems. The process of transformation leads to a transformation process from known to proven conclusions, and it can more effectively test logical reasoning ability, algebraic reasoning ability, and the ability to use related knowledge and methods to analyze problems and solve problems. There are many ways to solve inequalities. This article describes the use of construction method to verify inequality for reference.
