通过对文[1]阅读,笔者学习了该文作者提出的通性通法——三角代换法.然而,经笔者思考后还发现,这几个例题还存在另一种很实用的通法,即化齐次法.化齐次法是一种通过构造关系式(等式或不等式)两边各项的次数相等,转化为齐次式,从而实现解题目标的一种数学转化策略.此法具有广泛的应用价值,笔者将利用这种方法再来分析文[1]中的几个高考最值问题,与读者交 Through reading [1], I studied the general method - the triangle substitution method proposed by the author, however, after the author’s thinking, I also found that there are still some other practical methods , That is, the homogeneous method is a mathematical transformation strategy by constructing the equality of the terms (equality or inequality), the conversion into homogeneous, in order to achieve the goal of solving the problem. Act has a wide range of applications, the author will use this method to analyze the paper [1] in the most value of the college entrance examination, and the reader to pay
