不等式问题贯穿于整个高中数学的始终,诸如集合问题,方程(组)的解的讨论,函数定义域、值域、单调性的研究等,无一不与不等式有着密切的联系.选择恰当的方法会使我们的解题简洁明了.本文旨在归纳常见不等式的解法,以帮助同学们在复习时明确思路. Inequality runs through the entire high school mathematics, such as the problem of set, the discussion of the solution of equations (groups), the function domain, the range of values, the study of monotonicity, and so on are all closely connected with the inequality.Select the appropriate method Will make our problem simple and clear.This paper aims to summarize the common inequality solution to help students clear thinking in the review.
