证明不等式常用的方法有比较法、综合法、分析法、利用重要的不等式等。学生在解形式比较“标准”的不等式证明题时,一般容易寻到解题思路,但对一些形式“不大标准”的不等式证明题,往往打不开思路。以下介绍了几种打开不等式证明思路的思考方法。 The methods commonly used to prove inequalities include comparison methods, synthesis methods, analysis methods, and use of important inequalities. When students solve inequalities in the form of “standard” inequalities, it is generally easy to find the problem-solving ideas, but for some forms of “inconsequential” inequality, there is often no way of thinking. The following presents several ways of thinking about opening up inequalities.
