用坐标法定义向量的内积外积 空间解析几何新体系之一

THE DEFINING OF THE INNER PRODUCT AND OUTER PRODUCT OF VECTOR BY COORDINATE METHOD——One of the Systems on Space Analytic Geometry

本文首先用坐标法定义了向量的内积外积,然后证明了坐标法定义与向量法定义等价。这样做简化了内积外积各种运算规律的证明。

In this paper, we first define the inner product and out pro-duct of vector by coordinate method. Then, we prove that the definition of coordinate method and that of vector method are equivalent. Thus it simplifies the proofs of operational rules on the inner product and out product.
