同学们对一个代数不等式的理解,一般更注重于它的代数证明,而内隐在其背后的丰富的图形直观背景,则往往疏于挖掘,这不能不说是一种遗憾.实际上,很多代数不等式,不但可以通过代数的方法予以证明,而且还蕴含形象的几何意义,如果我们面对一个代数不等式,能够积极探寻其图形解释,不但可以加深对不等式的理解程度,而且还别具趣味.本文仅从图形的面积关系,来审视一些代数不等 The students’ understanding of an algebraic inequality generally focuses more on its algebraic proofs, and the implicit background behind its rich graphical intuition is often neglected, which is a pity. In fact, many Algebraic inequality, not only can be proved by algebraic method, but also contains the geometric meaning of the image. If we face an algebraic inequality, we can actively explore its graphical interpretation, not only can deepen the understanding of inequality, but also interesting. This article examines only algebra from the area of ​​the graph
