圆锥曲线是中学数学知识的一个重要交汇点,它常与函数、方程、导数、不等式、数列、平面向量等内容交叉渗透,知识跨度大,题型新颖别致、解法灵活,思维抽象强,能力要求高,它既是高考的热点题型,又是颇难解决的重点问题,在高考中占据着举足轻重的地位.近些年,高考对圆锥曲线的考查总体难度有所降低.ZHONGDIAN NANDIAN重点难点重点:熟练掌握求曲线方程的常用方法,会根据曲线方程研究平面曲线的性质,主要涵盖动点的轨迹问题、定点定值问题、参数取值 Conic curve is an important meeting point of middle school mathematics knowledge. It often penetrates with function, equation, derivative, inequality, sequence, plane vector and so on. The knowledge span is large, the topic is novel and unique, the solution is flexible, the thinking is abstract and the ability requirement High, it is both a hot topic type of college entrance examination, but also difficult to solve the key issues in the college entrance examination occupy a pivotal position.In recent years, college entrance examination of the conic curve overall difficulty has decreased.ZHONGDIAN NANDIAN Key Difficulties Focus: Familiar with the commonly used method of finding a curve equation, the curve of the nature of the plane curve will be studied, covering the trajectory of moving points, fixed point fixed value, parameter values
