对于恒成立问题,一些学生经常是束手无策,不知道从哪里下手,找不到问题的突破口,因而感觉十分困难.如果运用方程和函数思想,采用换元、化归、数形结合的思想方法,其实恒成立问题是不难解决的.恒成立问题有利于考查学生的综合解题能力,也是历年高考的一个热点.本文就高中数学恒成立问题的求解策略作一些归纳和总结,以飨读者.
For constant establishment of the problem, some students are often helpless, do not know where to start, can not find a breakthrough point of the problem, and thus feel very difficult.If the use of equations and function ideas, the use of yuan, return, the combination of mathematical methods, In fact, the establishment of a permanent problem is not difficult to solve .Constructing the problem is conducive to the establishment of constant problem-solving ability of students, but also a hot spot for the college entrance examination throughout the year.This article on high school mathematics constant problem-solving strategies to make some summaries and conclusions, readers.
