距离问题的统一处理

A Unified Approach in Distance Problem

利用Cauchy-Schwartz不等式统一处理点到直线的距离、点到平面的距离及n维空间中点到超平面的距离问题.

Using Cauchy-Schwartz inequality,this paper discusses the distance between a point and a line,the distance between a point and a plane,and the distance between a point and a hyper plane in an n-dimensional space.
