单词 | vector product |
释义 | vector product矢量积, 叉积 vector product vector product n.Mathematics (名词)【数学】 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&9{=}.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 |
