解析几何是历年各地高考的重头戏,也是近年来传统的压轴题之一.因此,考生们面对这样的题目,大多数都打退堂鼓,少有人能做到履“薄冰”而不觉惧,临“深渊”而不觉危的.下面笔者对高考涉及的或平时遇到的圆锥曲线问题进行分类评说,期望从中总结的一般框架能化作阶梯,对考生登上高峰有所帮助.1点的轨迹方程问题点的轨迹方程问题是圆锥曲线问题的基本考点,一般来说都会比较简单,主要考查考生分析问题、获 Analytic geometry is the highlight of the college entrance examination over the years, but also one of the traditional finale in recent years.Therefore, the candidates face such a problem, most of them have to back off, few people can do to play “thin ice” without fear , Pro “abyss ” without feeling critical. The following author on the college entrance examination involved in or concurrency problems encountered in the classification of commentary, expect to sum up the general framework can be turned into a ladder, to peak the candidates help .1 point trajectory equation problem trajectory equation point problem is the basic test conical problem, in general, will be relatively simple, the main test candidates to analyze the problem, was
