文[1],[2]介绍了用向量法判定直线与圆锥曲线位置关系的两种方法,受文[1],[2]的启发,笔者发现直线与圆锥曲线位置关系的又一向量判别
In [1], [2], two methods to determine the linear relationship between the straight line and the conic curve are introduced by vector method. Inspired by [1] and [2], the author finds another vector discriminant between the linear and the conic
