1.教材背景分析1.1教材的地位和作用《三角函数模型的简单应用》是高中数学新课标人教A版必修4的第一章最后一节的第一课时,其目的是让学生感受到三角函数在解决具有周期性变化规律的实际问题中的作用,体验三角函数与日常生活的联系,增强应用意识,初步掌握在实际问题中建立函数模型的基本方法.本节中教材共设置了4个例题,循序渐进地从四个层次来介绍三角函数模型的应用.经过比较,为了凸显学生主体地位,使学生能够更快速地融入课
1. Teaching material background analysis 1.1 The status and role of teaching material “The simple application of trigonometric function model” is a high school mathematics new curriculum standard to teach people A version of compulsory 4 the first chapter last chapter of the first class, its purpose is to enable students to feel Trigonometric function in solving the problem of cyclical changes in the role of the actual experience of trigonometric functions and daily life, enhance the sense of application, preliminary master the practical problems in the establishment of the basic function of the model in this section a total of 4 A case study, the application of the trigonometrical function model is introduced step by step from four levels.After comparison, in order to highlight the dominant position of students and enable students to integrate lessons more quickly
