圆锥曲线中,关于直线对称问题,主要考查学生对所学知识的综合运用能力,由于此类问题中的直线(曲线)在动,曲线上关于直线的对称点也在动,且解题过程中一般要涉及两个或多个参数,学生在解答时,往往抓不住主要矛盾,对合理运用动静条件感到无从下手或解题思路混乱,因此本文就此问题
In the conic section, about the symmetry of the straight line, we mainly examine students’ comprehensive abilities in applying the learned knowledge. Since the straight line (curve) in such problems is moving, the symmetry point of the straight line on the curve is also moving, and the problem solving process is in progress. Usually involves two or more parameters, the students often cannot grasp the main contradiction when answering, and have no way to start or solve the problem.
