化归的思想方法是解决数学问题的一种最基本的思想方法.所谓“化归”就是转化的意思.数学问题中的化归思想方法就是将所要解决的数学问题,利用变形等方法转化为一个已经解决的或比较容易解决的问题,从而使得原问题得到解决的一种方法.所以,化归的原则是:化难为易,化繁为简,化未知为已知,化曲为直,等等.其实,在高中数学的教学中,基本上每一个新知识的学习,都是通过把它转化为已学过的旧知识去解决,很多数
The ideological method of transformation is one of the most basic ways of thinking in solving mathematics problems. The so-called “returning to transformation” is the meaning of transformation. The method of transformation in mathematics problems is the mathematical problem to be solved, and the method of deformation is used. It is a method that has already been solved or that can be solved easily, so that the original problem is solved. Therefore, the principle of transformation is: to make it difficult to change, to simplify and simplify, to change the unknown to known, to change the Straight, etc. In fact, in the teaching of high school mathematics, basically every new knowledge is learned by transforming it into old knowledge that has already been learned.
