一、高考目标(1)能用坐标法解决一些与圆锥曲线有关的简单几何问题(直线与圆锥曲线的位置关系)和实际问题;(2)进一步感受数形结合的思想、函数与方程思想、等价转化思想。二、要点再现1.直线与圆锥曲线的位置关系从几何角度看,可分为三类:有两个公共点,有一个公共点及没有公共点。从代数角度看,将表示直线的一次方程和表示圆锥曲线的二次方 First, the college entrance examination objectives (1) coordinate method can be used to solve some of the simple geometric problems related to the conic (linear and conical position of the relationship) and the actual problem; (2) further experience the idea of ​​combining numbers, functions and equations of thought, Equivalent conversion thinking. Second, the point of reproduction 1. The linear and conical position relationship from a geometric point of view, can be divided into three categories: There are two common points, there is a common point and no common point. From an algebraic perspective, it will represent a linear equation and a quadratic curve representing the conic
