数学思想方法是数学基础知识、基本技能的本质体现.本文对“解三角形”中常用的数学思想方法进行归纳介绍,供同学们参考.一、数形结合思想数形结合思想是最重要的数学思想方法之一.锐角三角函数概念的建立以及推理论证,都是通过数形结合的思想实现的.例1(2005年舟山市中考题)课 Mathematical thought and method are the basic manifestations of basic mathematics knowledge and basic skills. This paper summarizes the commonly used mathematics thoughts and methods in “solving triangles” for students’ reference. First, the combination of number and shape is the most important mathematics. One of the methods of thinking. The establishment of the concept of the acute-angle trigonometric function and the deduction of theoretical evidence are all achieved through the idea of ​​combination of numbers and shapes.
