函数图象上两个动点之间的距离的最值(取值范围)问题归纳起来主要有三种类型:(1)两个动点分别在一个函数图象和一条直线上;(2)两个动点分别在一个函数图象和一个圆锥曲线上;(3)两个动点分别在两个函数图象上.下面通过例子具体谈一谈函数中两动点间的距离的最值(取值范围)的探求方法.1.两个动点分别在一个函数图象和一条直线上两个动点P,Q分别在一个函数图象和一条直线l上,求这两个动点P,Q之间的距离的最值(取
There are mainly three types of problems summarized in the function image: (1) Two moving points are respectively on a function image and a straight line; (2) Two (3) two moving points in the two function images, respectively, by way of example to talk about the specific value of the distance between two moving points in the function of the value The range of values) of the exploration method .1 two moving points respectively in a function image and a straight line two moving points P, Q in a function image and a straight line l, find the two moving points P , Q the distance between the value of the (take
