直线与圆锥曲线的位置关系在高考中的地位举足轻重,应扎扎实实地搞好这方面的复习,注意领会培养,强化圆锥曲线内容渗透出的数学思想方法,比如:等价转换、函数与方程、数形结合、分类讨论等数学思想,以及向量法、坐标法、定义法、待定系数法、参数法等数学方法,圆锥曲线是不折不扣的数学思想和方法的集中营,这也是高中阶段学习圆锥曲线的真谛.
The relationship between the position of the straight line and the conic should play a decisive role in the college entrance examination. We should do a good job in reviewing this aspect in a down-to-earth manner, pay attention to comprehending and cultivating and strengthening the mathematical ideas and methods permeated by conic contents, such as equivalence transformation, functions and equations, Mathematical methods such as vector method, coordinate method, definition method, undetermined coefficient method, parametric method and so on. Conic curve is a concentration camp of mathematical ideas and methods, which is also a high school study The true meaning of the conic curve.
