三角函数是描述周期现象的数学模型,是高中数学知识体系的重要组成分支之一,同时也是解决实际问题有效工具。三角函数章节主要介绍了任意角、弧度、任意角的三角函数,以及三角函数的图像和性质等知识内容。通过研析三角函数案例解析方法发现,在解析三角函数案例过程中,需要运用到多样解题思想方法,对锻炼和培养同学 Trigonometric function is a mathematical model to describe the periodic phenomenon, which is one of the important branches of high school mathematics knowledge system and an effective tool to solve practical problems. The chapter of trigonometric functions mainly introduces the trigonometric functions of arbitrary angle, radian and arbitrary angle, as well as the image and nature of trigonometric functions. By analyzing the trigonometric function case analysis method, we found that in the process of analyzing the trigonometric function cases, we need to apply a variety of thought-solving methods to exercise and train students
