考点题例圆锥曲线方程是平面解析几何的核心内容,同时也是历年高考的重点考查内容.不但选择题、填空题离不了,解答题中也常常有一道大题,而且有时还以压轴题出现.这部分内容约占17-22分,万万不可忽视.特别注重对圆锥曲线定义、标准方程、几何性质(离心率、准线方程、渐近线方程等)的考查,对曲线与方程的知识的要求较高.既深入地考查了学生对基本概念的理解,基本方法的掌握情况,同时也考查了考生的变形计算能力.解答题的综合性很强,仅以2006年18套试题卷为例,解答题常常与平面向量、数列、不等式、函数交汇,特别是圆锥曲线与平面
Test point examples Conic equation is the core content of plane analysis geometry, and it is also the key examination content of previous college entrance examinations. Not only the multiple-choice questions, fill in the blank questions can not be separated, the answer questions often have a big question, and sometimes the finale problems appear. This part of the content of about 17-22 points, must not be ignored. Pay particular attention to the definition of conical curve, standard equations, geometric properties (centrifugal rate, quasi-linear equation, asymptote equation, etc.) of the examination, the knowledge of the curve and equation The requirements are relatively high. Both in-depth examination of the students’ understanding of the basic concepts, the mastery of the basic methods, as well as the examinee’s deformation calculation ability. The comprehensiveness of the answer questions is very strong, only the 18 sets of questions in 2006 are For example, answer questions often intersect with plane vectors, series, inequalities, and functions, especially conic curves and planes.
