The Attempt at a Solution

i know this one
AxB=i(a2b3-a3b2)+j(a3b1-a1b3)+k(a1b2-a2b1)

There is the way involving the angle between the two vectors (which you have used in some other problems you posted here.)

Wikipedia says:
\mathbf{a}\times\mathbf{b}= \begin{vmatrix}<br /> \mathbf{i} &amp; \mathbf{j} &amp; \mathbf{k} \\<br /> a_1 &amp; a_2 &amp; a_3 \\<br /> b_1 &amp; b_2 &amp; b_3 \\<br /> \end{vmatrix}
(but that's equivalent to what you already mentioned)
