vector product (cross product)


The multiplication of two vectors to produce a vector.
The vector product of A and B (usually written A×B) is a vector whose magnitude is ABsin, in which A and B are the magnitudes of A and B and is the angle between A and B. The direction of the resulting vector points in the direction in which a righthand screw would move when turning from vector A toward vector B. It is at right angles to both A and B.
