函数思想就是用联系与变化的观点提出数学对象,抽象其数学特征,建立函数关系,并利用函数的特质来研究、解决问题的一种数学思想方法.函数是高中数学的重要内容之一,也是高考的重点.函数思想贯穿于整个高中数学学习过程,变化多,联系广,应用灵活,函数与方程、不等式、数列等知识的联系常常是编制高考数学试题的出发点和落脚点.下面就函数思想的应用作简单的介绍,希望能给同学们的学习带来 Function idea is to use mathematics object from the point of view of connection and change, abstract its mathematical characteristics, establish function relations, and use the characteristics of the function to study and solve the problem of a mathematical thinking method. Function is one of the important contents of high school mathematics, and also The focus of the college entrance examination. Function thinking throughout the high school mathematics learning process, change, contact, application flexibility, function and equations, inequalities, series and other knowledge is often the starting point and the end result of the preparation of college entrance examination mathematics test questions. Application for a brief introduction, hoping to bring learning to the students
