vector product

vector-product的词性：
n.Mathematics （名词）【数学】

1. A vector, C, that has magnitude equal to the product of the magnitudes of two vectors, A and B, and the sine of the angle between A and B. It is perpendicular to the plane of A and B and in a right-handed coordinate system directed so that a right-handed rotation about C carries A into B through an angle not greater than 180⁼.Also called cross product
向量积，叉积：向量C，其大小与A和B两个向量以及A和B之间的角度的正弦三者的乘积相等。它与A和B所在的平面相垂直而且处于按顺时针旋转的正坐标系内，因此C向量的顺时针旋转通过一个不大于180°的角度把A带入B中也作 cross product
