直线和圆的方程、圆锥曲线方程都属于解析几何内容,是每年必考的内容之一,在试卷中约占总分的20%,并且每年必定有一个大题.其中直线与圆的方程、直线与圆锥曲线的位置关系、圆锥曲线的几何性质等,是考查的重点.本文对2008年高考试题中的解析几何试题作一剖析,以供读 The equations of linear and circular equations and conic equations are all part of the analytical geometry and are one of the contents that must be considered each year. They account for about 20% of the total scores in the test paper, and there must be a big question every year. Among them, the equations of straight lines and circles, The positional relationship between the straight line and the conic section and the geometrical properties of the conic section are the focus of the examination. This article gives an analysis of the analytical geometry questions in the 2008 high exam questions for reading.
