平面解析几何研究的是曲线问题,运用的是代数方法,渗透的是数形结合思想,是中学数学知识的一个重要交汇点,当然也是高考考查的重点和难点之一.分析和研究近年的高考解析几何解答题,我们可以发现如下特点:1重点突出,即对圆锥曲线的特征量(焦点、准线和离心率)的计算,曲线方程的求法,直线、圆与圆锥曲线的交点问题的考查几乎没有遗漏,既考查支撑学科知识体系的主干知识,
Plane analytic geometry is the curve of the problem, the use of algebraic method, the infiltration of the number of conjunctions, is an important intersection of mathematical knowledge of high school, of course, is one of the key and difficult point of college entrance examination.Analysis and research in recent years, college entrance examination Analyze the geometric solution, we can find the following features: 1 highlights, namely the calculation of the characteristic amount (focus, alignment and eccentricity) of the conic curve, the calculation of the equation of the curve, test of the intersection of the straight line, the circle and the conic curve Almost no omission, both to examine the knowledge of the backbone of the discipline system of knowledge,
