化归是指问题之间的相互转化.其具体表现形式是要解决问题 A,可将它转化为较为容易解决的问题B(问题 A 与问题 B 之间存在某种关系),从而解决问题 A.化归是解决数学问题的一种重要的思想方法,几乎所有数学问题的解决都离不开化归,只是所体现的化归形式不同罢了.在实际教学过程中,笔者常常发现学生在具体运用化归的思想方法解决问题时存
Conversion refers to the mutual transformation between problems, and its concrete manifestation is to solve the problem A, which can be transformed into a problem B that is easier to solve (there is a relationship between the problem A and the problem B) to solve the problem A It is an important way to solve the problem of mathematics.Almost all the problems of mathematics can not be solved without the return to normalization.On the actual teaching process, The way to change the way of thinking to solve the problem
