WebThe length of the cross product of two vectors is directly proportional to the length of each vector as well as the sine of the angle they span. In the first case, the angle spanned between a vector and itself is $0$, and $\sin(0)=0$, so that we obtain a vector of length … WebWe can calculate the Cross Product this way: a × b = a b sin (θ) n a is the magnitude (length) of vector a b is the magnitude (length) of vector b θ is the angle between a and b n is the unit vector at right angles to both a and b So the length is: the length of a times the length of b times the sine of the angle between a and b,
