化归法,就是采用某种手段将复杂、难解的数学问题转化为简单、容易理解的问题,从而使数学问题得到解决。这是一种十分灵活的数学思想方法,在高中数学解题过程中多有体现,主要包括分类讨论思想、数形结合思想、函数与方程的思想等,而三角函数作为高中数学最重要的部分之一,具有很强的综合性,如何巧妙利用化归法解决高中数学三角函数题,本文结合例题进行阐述。
The method of transformation is the use of some means to transform complex and difficult mathematical problems into simple and easy to understand problems, so that the mathematical problems can be solved. This is a very flexible way of thinking in mathematics. It is reflected in the process of mathematics in high school mathematics. It mainly includes the ideas of classification and discussion, the idea of combining numbers and shapes, and the ideas of functions and equations. The trigonometric function is the most important part of high school mathematics. One, with a strong comprehensive, how to skillfully use to resolve the high school mathematics trigonometric problems, this article describes the example.
