圆锥曲线题在高考中扮演着压轴题的角色,这种题目横向入手宽,上手易,只是纵向难度大,深入难,解到底更难,究其原因是因为圆锥曲线题目综合性比较强,它常常综合考察圆锥曲线、函数、方程、不等式、导数等知识,集数形结合、方程与函数、分类与整合、化归与转化、特殊与一般等数学思想于一身,由此衍生出的计算量往往比较复杂,这也是师生常常感觉圆锥曲线题目“易想难 Conic curve in the college entrance examination plays the role of pressure axis title, this topic horizontal start wide, easy to get started, but the longitudinal difficulty, in-depth difficult, the solution more difficult in the end, the reason is because of the comprehensive conic curve is relatively strong, it Often it is a comprehensive study of conics, functions, equations, inequalities, derivatives and other knowledge, set number combination, equations and functions, classification and integration, conversion and transformation, special and general mathematical ideas in one, the resulting calculation Often more complicated, this is also the teachers and students often feel the conic problem ”easy to think hard
