在解答解析几何的题目时如何节省运算量很关键.直线与圆锥曲线相关问题也是这样.本文试图结合实际例子,总结其中常见的不求交点坐标也能解题的几种方法.
The key to solving this problem is to solve the problem of how to solve the problem of geometry analysis. This is also the case with the straight line and the conic .This paper attempts to combine several practical examples to summarize some common methods which can solve the problem without the intersection coordinates.
