一、引言圆锥曲线是解析几何中的重点,也是高中数学的重点之一,也是历年高考数学试题命制的热点和重点;圆锥曲线试题特别是综合题在高考中常处于压轴题的位置,题型变化灵活,能考察学生的能力立意和思维空间,是出活题,考能力的典范;由于向量、导数等新内容的充实,圆锥曲线试题逐渐向多元化、交汇型发展,除了传统的求圆锥曲线方程,直线与圆锥曲线的位置关系外,还增加开放性、探索性问题等;下面将对近年考题中的圆锥曲线题型进行分析探索。二、圆锥曲线的考点和难点:圆锥曲线考查的范围很广,但其主要考查学生对圆锥曲线的定义,性质等基础知识的掌握,还充分考查了各种数学思想方法及一定的推理能力和运算能力,因此这类问题成为高考命题的热点,也是同学们主要的难点;但我们会发现它就考
I. INTRODUCTION Conic curve is the focus of analytical geometry, but also one of the key high school mathematics, but also calendar years of mathematics test questions the focus and focus; Conic curve test questions, especially in college entrance examination is often in the finale of the title position, Change flexible, can examine the ability of students conception and thinking space, is a living model, test ability; due to the vector, derivative and other new content is enriched, conical curve test gradually diversified, convergent development, in addition to the traditional conical Curve equation, the relationship between the straight line and the conic curve, but also increase the openness, exploratory issues, etc .; the following will be in the test cones in the test questions to explore. Second, the conic curve test points and difficulties: Conic curve test a wide range, but its main test of students coning curve of the definition, nature and other basic knowledge mastery, but also a full examination of a variety of mathematical thinking and a certain amount of reasoning ability and Computing power, so these questions become the hot topic college entrance examination, but also the main difficulty for students; but we will find it to test
