序言解析几何在高中教材中的地位非常突出,它通过坐标法巧妙地将代数与几何结合在一起,它与三角、向量、不等式等知识点的结合比较密切,是高考考查的重点内容.解析几何在高考中考查的重点是它的核心方法——坐标法以及重要思想——数形结合思想,主要从代数和几何两个角度来考查直线和圆、圆锥曲线的定义与标准方程以及几何性质:一是考查曲线与方程的求法,二是 Preamble Analytic Geometry in high school teaching materials in the very prominent position, which coordinates by skillfully algebra and geometry together, it and triangle, vector, inequality and other knowledge points of the more closely, is the focus of college entrance examination test. The key point in examining the college entrance examination is its core method - the coordinate method and the important idea - the idea of ​​combining numbers and shapes, and examines the definitions and standard equations of straight lines and circles, conic curves and their geometric properties mainly from two aspects of algebra and geometry: First, test the curve and equation of the method, the second is
