This command works in CAS View only.

Cross[ <Vector u> , <Vector v> ]: Calculates the cross product of u and v.; Example:
Cross[{1, 3, 2}, {0, 3, -2}] yields {-12, 2, 3}.

If a vector contains undefined variables, it yields a formula for the cross product.

Example: Cross[{a, b, c}, {d, e, f}] yields "{b f - c e, -a f + c d, a e - b d}".
