在证明不等式时,常用的方法有:(作差、作商)比较法、分析法和综合法。而综合法是贯穿高中数学证明题始终的。只要掌握问题的本质,就能在证明题中起到事半功倍的效果。本文从一节课堂实录(部分)中体悟综合法在证明不等式中的妙用。一、情境引入师:前面我们学过一种最最基本也是最最常用的证明不等式的方法,也就是比较法,比较法常用的有作差和作商两种方式。我们一起来做做这些题目。 In proving inequalities, commonly used methods are: (as bad, business) comparison, analysis and synthesis. The comprehensive law is consistent throughout the high school mathematics testimony. As long as you grasp the essence of the problem, you can play a multiplier effect in the proof questions. This article from a lesson record (part) comprehend the magical effect of the synthesis method in proving inequality. First, the situation introduced division: In front we have learned one of the most basic and most commonly used method to prove inequalities, that is, comparative method, comparative method commonly used to make errors and to do business in two ways. Let’s do these topics together.
