“转化”思想是数学思想方法中的精髓,“转化”思想是指把要解决的问题,转化为已经解决或者较容易解决的问题的一种数学思想。通过转化可使问题由繁到简,由难到易,由暗到明。在解题过程中运用转化思想时通常遵循以下原则:一、熟悉化原则熟悉化原则就是将我们遇到的问题,通过变换问题的条件或结论,转化为我们比较熟悉的问题来处理。 The idea of ​​“transformation” is the quintessence of the method of mathematics. The “transformation” idea refers to a kind of mathematical thought that transforms the problem to be solved into a problem that has been solved or that is easier to solve. Through the transformation, the problem can be changed from complexity to simplicity, from difficult to easy, from dark to bright. The following principles are generally used when applying transformation ideas in the process of solving problems: 1. Familiarization principles The principle of familiarization is to turn the problems we encounter into the problems we are more familiar with by changing the conditions or conclusions of the problems.
