客观事物在不断地运动变化,事物之间在互相转化.反映在数学上的转化思想就是在处理问题时,把待解决或难解决的问题,通过某种转化,变为一类已经解决或比较容易解决的问题,最终求得原问题的解决.波利亚指出:“解题过程就是不断变更题目的过程”.转化思想就是要求我们换一个角度去 Objective things are continuously moving and changing, and things are transforming each other. Reflected in mathematics, the idea of ​​transforming is to solve the problems that need to be solved or difficult to solve through a certain transformation and become a class of solutions or comparisons. The problem that is easy to solve is to finally find the solution to the original problem. According to Polya, “The problem-solving process is the process of constantly changing the subject.” Transforming thinking is to ask us to change the angle.
