“解析几何”是高中数学的重要内容之一 ,它的知识点多、涉及面广、思想丰富、综合性强 ,很容易与其它知识建立联系 .正因为如此 ,每年的高考对解几问题的考查都占有相当大的比例 ,可谓常考常新 .尤其是“导数”和“向量”进入中学数学教材之后 ,拓宽了高考对解几问题的命题空? “Analytic Geometry” is one of the important contents of high school mathematics. It has many knowledge points, wide coverage, rich thoughts, and strong comprehensiveness. It is easy to establish links with other knowledge. Because of this, the annual college entrance examination solves several problems. Examinations occupies a considerable proportion, can often be described as often new. In particular, “derivative” and “vector” into the middle school mathematics textbooks, broaden the college entrance examination on the solution of several issues of the proposition empty?
