等价转化的思想是中学数学四大思想方法之一 ,表现在教材中就有互化等。运用数学思想方法解题是教学的一个难点 ,本文将归纳出高中数学中六种常见的互化 ,并结合近年高考题加以说明 ,供参考。一、原函数与反函数的互化ｙ =ｆ(ｘ) ｘ =ｆ(ｙ) (通常写成ｙ =ｆ- 1 (ｘ) ) ,特别 The idea of ​​equivalent transformation is one of the four major ways of thinking in middle school mathematics. There is mutualization in the teaching materials. The use of mathematical thinking methods to solve problems is a difficult teaching, this article will summarize the six common high school mathematics, and combined with recent college entrance examination questions to illustrate for reference. First, the interaction of the original function and the inverse function y = f (x) x = f (y) (usually written as y = f- 1 (x)), special
