随着新课程标准的不断推进与深入,高考对解析几何的要求也随之发生了很大的变化,对圆的要求大大提高,对圆锥曲线的要求则相对降低。因此,近几年圆的交汇性问题已成为高考命题的一个新热点。下面精选2014年高考的部分试题并予以分类解析,旨在探索题型规律,揭示解题方法。一、圆与点、直线、圆的交汇(一)圆与点的交汇
With the constant advancement and deepening of the new curriculum standards, the requirements for the analytic geometry of the college entrance exam have also undergone tremendous changes. The requirements on the circle are greatly raised, and the requirements on the conic curve are relatively lower. Therefore, in recent years, the problem of round exchange has become a new hot topic in college entrance examination. Below selected 2014 college entrance examination part of the test and classification analysis, to explore the type of questions to reveal the problem-solving methods. First, the circle and the point, the line, the intersection of the circle (a) the intersection of the circle and the point
