A good answer might be:

What is the cross product of (0, -1, 2)T with (1, 2, 1)T ?  


Another Evaluation

Evaluation follows the same pattern as before, but the second and third rows have been swapped.

This is the negative of the previous result, demonstrating that

u × v   =   -(v × u) .

(You saw this before, only done with geometrical vectors).

QUESTION 14:

What does the determinant-like thing look like when you take the cross product of a vector by itself?
