这是说 cross product （即叉乘，或向量积） axb 还是向量，它的方向依 right hand rule（右手准则）确定，即用右手的中指、食指和拇指分别表示a，b 和 axb，它们作成一个正交标架。

2. Algebraic Properties of the Cross Product u×vis orthogonal to bothuandv.|u×v|=|u||v|sinθ. right hand side rule u\times vis perpendicular touandv. The length ofu\times vis|u\times v|=|u||v|sin\theta. The direction is given by the right hand side rule. (u\times v)\cdot...
right hand rule：右手四指先沿着第一个矢量a，向第二个矢量弯曲，大拇指的方向就是cross product的方向
Learn how to find the cross product or vector product of two vectors using right-hand rule and matrix form. Also, get the definition, formulas, properties and example of vector product at BYJU’S.
right-hand rule for vector cross productThe ordinary, or dot, product of two vectors is simply a one-dimensional number, or scalar. In contrast, the cross product of two vectors results in another vector whose direction is orthogonal to both of the original vectors, as illustrated by the rig...
用右手从a的方向握向b的方向，那么大拇指所指的方向即为叉积的方向，你可以想象一下直角坐标系的x、y、z轴，从x握向y，大拇指方向为z，图解参考下图
c=axb,c垂直于a,b确定的平面。右手系： 右手握拳竖起大拇指， 右手四个手指是从 a 到 b 的旋转方向（旋转角度最小<=180度），大拇指方向则为 c 的方向。
xaxb+yayb+zazb=AC⋅BCcosθ 离矢量也就是一步之遥 设a→⋅b→=xaxb+yayb+zazb=|a||b|cosθ dot product,可以快速判断θ是否为直角,当a→⋅b→=0时 下面是见证时刻的奇迹 已知一个矢量a→,比如(1,2)或(3,4,5),想要找到与这个矢量垂直的线(二维)或面(三维)方程,根据余弦定理...
Perpendicular Vectors and the Right-Hand Rule In the description of the cross product, it is stated that the direction of the cross product is perpendicular to the plane spanned by vector a and vector b. But this leaves two possibilities: It might point out of t...
