1编写理念本章把知识内容定位在“函数的应用”,主要内容是两部分:一是介绍函数与方程的一些关系,另一是函数模型的应用举例.试图通过本章的学习,让学生初步领略到用函数模型及函数思想去解决问题的方法,从而进一步加深对函数重要性的认识.现结合本章(函数的应用),谈谈几点编写 1 Writing Concepts This section positions the knowledge content in the “Application of Functions”. The main contents are two parts: one is to introduce some relations between functions and equations, and the other is to apply examples of function models. To try to gain a preliminary understanding of students through the learning of this chapter. To use the function model and function idea to solve the problem, so as to further deepen the understanding of the importance of the function. Now with the chapter (application of the function), talk about a few points to write
