化归思想既是数学中常见的一种思想方法,也是一种最基本的解题策略,更是一种有效的数学思维方式。所谓化归思想,就是在研究和解决有关数学问题时,采用某种手段将问题通过变换使之转化,进而解决问题的一种方法。运用归思想解决问题,一般是将复杂问题通过变换转化为简单问题,将难解的问题通过变换转化为容易求解的问题,将未解决的问题通过变换转化为已解决的问题。一、在简单计算中感知化归思想在学习新知识的时候,人们往往会用已有的知识去认 Returning to thought is not only a common way of thinking in mathematics, but also a most basic problem-solving strategy, but also an effective way of thinking in mathematics. The so-called return to thought, that is, in the study and solve the mathematical problems, the use of some means to transform the problem to transform, and thus a solution to the problem. To solve the problem by using the idea of ​​return, the general problem is to transform complex problems into simple problems through transformations, transform difficult problems into easily solved problems through transformations, and transform unresolved problems into resolved problems through transformations. First, the perception in the simple calculation to return to the thought of learning new knowledge, people tend to use the existing knowledge to recognize
