向量积在定理证明和公式推导中的运用

Application of the Cross Product in Theorem Proving and Formula Derivation

向量积(或叉积)是向量代数中一种重要的乘法运算.运用向量积来推导数学中的一些定理和公式,解决左(右)手标架和平面直线方程的建立等相关问题有其独到之处.

Cross product is an important multiplication operation for vector algebra. This paper investigates and derives some theorems and formulas using cross product, such as solving the left（right） hand frame and establishing the plane linear equation. In the process of these problems solving, cross product has its unique advantage.
