用“放缩法”证明不等式在高考题和各地模拟题的压轴题中屡见不鲜,本文以具体题型为例,介绍了用“放缩法”证明不等式的几种常用策略,旨在探索题型规律,揭示解题方法.众所周知,放缩法是不等式证明的一种非常重要的方法,在高考题和各地模拟题的压轴题中屡见不鲜.所谓放缩法即是从不等式的一边着手,用不等式的传递性等性质,
It is not uncommon to prove the inequality in the college entrance examination papers and simulation questions around the college entrance examination papers and the simulation questions all over the world by using the “scaling method”. This paper introduces several commonly used strategies to prove the inequalities by using " In the exploration of the type of questions to reveal the problem-solving method.As we all know, scaling is a very important method of inequality proved in the entrance exam questions and around the finale of simulation questions are commonplace.The so-called scaling method is inequalities side Proceed, with inequality and other nature of the transitivity,
