不等式是高中数学的重要内容,也是高考必考内容之一,考查的形式多样,题型灵活,需要高中生认真掌握相关知识,特别是一元二次不等式解法、分式不等式解法、绝对值不等式、柯西不等式等内容.我在教学过程中发现学生对解不等式,特别是证明不等式无从下手,解答很是费力.这说明学生只掌握课本的简单知识是不够的,相当多的题是由简单知识组合而成的,需要学生具有透过现象看本质的慧眼和能力.现在我就教学中遇到的一些不等式问题的解 Inequality is an important part of high school mathematics, but also one of the contents of the college entrance examination will be exam in a variety of forms, questions flexible, you need to master the relevant knowledge of high school students, especially quadratic inequality solution, fractional inequality solution, absolute inequality, Cauchy inequality, etc. I found that students in the teaching process of solving inequalities, especially to prove inequalities can not start, the answer is very laborious.This shows that students only grasp the simple knowledge of textbooks is not enough, a lot of questions are simple knowledge A combination of students needs to have the vision and ability to see the essence through the phenomenon.Now I am in the teaching of some inequalities encountered in the solution
