化归思想是数学中常用的一种重要思想,一般是指人们将待解决或难以解决的问题通过某种转化过程,归结到一类已经解决或比较容易解决的问题中去,最终求得原问题的解决的一种手段和方法.其本质就是转化.应用化归思想时要遵循三个基本原则:熟悉化原则,即将陌生的问题转化为熟悉的问题;简单化原则,即将复杂的问题转化为简单的问题;直观化原则,即将抽象问题转化为具体问题.其中化归方法是实现化归的关键.化归思想和方法在中学数学解 Returning to thought is an important idea commonly used in mathematics, generally refers to the people to be solved or difficult to solve the problem through some kind of conversion process, boiled down to a class of problems that have been resolved or relatively easy to solve, and ultimately seek the original The solution of the problem is a means and method of its essence is the transformation of the application of thought to follow to follow three basic principles: the principle of familiarization, that is, unfamiliar problems into familiar problems; the principle of simplification, that is, the problem of complex transformation As a simple problem; the principle of visualization, that is, abstract problems into specific problems, of which the return to the method is to achieve the key to return to normalization of thought and methods in the high school mathematics solution
