vector product

1. A vector c , depending on two other vectors a and b , whose magnitude is the product of the magnitude of a , the magnitude of b , and the sine of the angle between a and b . Its direction is perpendicular to the plane through a and b and oriented so that a right-handed rotation about it carries a into b through an angle not greater than 180°. The notation for c is c = a × b .
