解析几何是高中数学的一个重要内容,它的基本特点是数形兼备,历来是高考的重点模块.从内容上看,高考主要考查两大类问题:一是根据条件,求出表示平面曲线的方程;二是通过方程,研究平面曲线的性质.其热点有:(1)以客观题的形式考查直线、圆、圆锥曲线的基本概念和性质;(2)求平面曲线的方程和轨迹;(3)直线、圆、圆锥曲线的有关元素计算、关系证明或
Analysis of geometry is an important part of high school mathematics, its basic feature is both number and shape, has always been the focus of the entrance examination module.From the content point of view, the college entrance examination mainly examines the two major categories of problems: First, according to the conditions, The second is through the equation, the study of the nature of the plane curve.The hot spots are: (1) in the form of objective questions to examine the basic concepts and properties of straight lines, circles, conic curves; (2) seeking plane curve equation and trajectory; ( 3) The calculation of the relevant elements of the line, circle, conic curve, the relationship between proof or
