This command works in CAS View only.

Cross[ <Vector u> , <Vector v> ]
Calculates the cross product of u and v.
For vectors u=(a,b) and v=(c,d) returns ad-bc (i.e. the z-coordinate of vector product of (a,b,0), (c,d,0)).
Example:
Cross[{1, 3, 2}, {0, 3, -2}] gives {-12, 2, 3}, the cross product of {1, 2, 3} and {0, 3, -2}.
