函数是高中数学的核心概念,也是中学数学中的基本概念.高中阶段不仅把函数看成变量之间的依赖关系,同时还用集合与对应的语言刻画函数。函数的思想方法贯穿整个高中数学课程.也是高考考查的重点内容.本文从四个方面来细细品位函数,通过对函数的宏观认识和微观分析,帮助正在复习迎考的高三学子们更好地理解函数概念的本质,优化该模块的学习效果.一、函数概念的发展历程在1 7世纪,对物体运动的研究已成了
Function is the core concept of high school mathematics, but also the basic concept of high school mathematics.In high school, not only the function as a dependent relationship between variables, but also with the collection and the corresponding language characterization function. Function thinking method runs through the entire high school mathematics curriculum is also the key content of college entrance examination examinations.This article from four aspects to the level of function, through the macroscopic understanding of the function and micro-analysis to help the senior high school students who are reviewing the examination better Understand the nature of the concept of function and optimize the learning effect of the module.First, the development of function concept In the 17th century, the research on the movement of objects has become
