摘要
由立体几何知识知道,空间两条异面直线的距离问题比较复杂。通过多元函数极值问题和向量问题两种方法,讨论空间两条异面直线的最短距离,并给出空间两条异面直线的距离公式。
As we know from solid geometry knowledge,it is very difficult to discuss the distance between two singular plane lines in space.In this article,we will introduce two functions about extreme value and vector questions of multivarite function.At last this article will discuss the shortest distance of singular lines,and giving distance formula of two singular plane lines in space.
