圆锥曲线是是高中数学的重点之一,也是近几年高考数学试题命题的热点和重点;它往往是综合题,在高考试卷中常处于压轴题的位置,题型变化灵活,能考查学生多方面运用能力,是出活题,考能力的典范;由于向量、导数等新内容的充实,圆锥曲线试题逐渐向多元化、交汇型发展.高考中,对于圆锥曲线的考试,很少单独考查它的定义、性质,往往是在此基础上,考查与其他知识点的组合,要想解决题目,就必须掌握一些综合 Conic curve is one of the high school mathematics focus, but also in recent years, college entrance examination mathematics test proposition hotspot and focus; it is often a comprehensive question, often in the college entrance examination papers in the finale of the title, flexible changes in questions, students can examine many aspects The ability to use, is a viable, a model of ability test; due to the vector, derivative and other new content enrichment, conical curve test gradually diversified, interdependent development.College entrance examination, conical curve test, it rarely seized it Definition, nature, is often based on this, examine the combination with other knowledge points, in order to solve the problem, we must master some of the synthesis
