直线与圆锥曲线是高中解析几何中的重要内容,它涉及函数方程、不等式、三角、向量等许多知识,直线与圆锥曲线联系在一起的综合题在高考中多以压轴题出现,主要涉及位置关系的判定、弦长问题、最值问题、对称问题、轨迹问题等,突出考查数形结合、分类讨论、函数与方程、等价转化等数学思想方法,因此直线与圆锥曲线的问题往往综合性强、计算能力要求高、难度大,是同学们学习上的难点之一,但同时也是高考的重点之一。
Linear and conic is an important part of high school analytic geometry. It involves many knowledge of function equation, inequality, trigonometry, vector and so on. The combination of straight line and conic curve appears mostly in the college entrance examination, mainly involving the position relationship The chord length, the most value problem, the symmetry problem, the trajectory problem, and so on, highlighting examining mathematical combination methods such as number combination, classification discussion, function and equation, equivalence transformation, etc., so the problems of straight lines and conic curves are often comprehensive , High computational ability, difficult, is one of the difficulties of students to learn, but it is also one of the key points of the college entrance examination.
