三角函数知识不仅是高中数学中的一部分重要内容,同时在测量,测绘工作,微积分,以及物理中振动,声音传播等的研究中都有着广泛的应用,而且通过这部分内容的学习,特别是通过三角公式的学习,学生的推理能力,运算能力都会有很大的提高。一、学习方法指导(1)熟记公式并理解其推导过程(2)多动手练习(3)多总结 Knowledge of trigonometry is not only an important part of mathematics in high school, but also widely used in surveying, surveying and mapping, calculus, vibration and sound propagation in physics. In addition, through this part of the study, especially Through the study of trigonometry formula, students’ reasoning ability and computing power will be greatly improved. First, the learning method guide (1) memorize the formula and understand the derivation process (2) hands-on exercises (3) and more summary
