vector productvector product
a vector perpendicular to each of two given vectors u and v and having magnitude equal to the product of the magnitudes of u and v and the sine of the angle from u to v
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 . Also called cross product .
c = a x b
