Description and formula for the Vector cross product

In one in the real coordinate space \(\displaystyle \mathbb {R}^{3} \) with the standard scalar product and the standard orientation applies to the cross product:

\( \vec{a}\; \times\; \vec{b} = \left[\matrix{a_1\\a_2\\a_3}\right] \times \left[\matrix{b_1\\b_2\\b_3}\right] = \left[ \matrix{a_2b_3-a_3b_2\\a_3b_1-a_1b_3\\a_1b_2-a_2b_1 } \right]\)


\( \vec{a}\; \times\; \vec{b} = \left[\matrix{1\\2\\3}\right] \times \left[\matrix{7\\8\\9}\right] = \left[ \matrix{2\cdot 9 - 3\cdot 8\\3\cdot 7 - 1\cdot 9\\1\cdot 8 - 2\cdot 7 } \right] = \left[ \matrix{-6\\12\\-6} \right] \)
