The cross product of two vectors, $(a, b, c)$ $(a, b, c)$ and $(d, e, f)$ $(d, e, f)$ , is given by: $(b f - c e, c d - a f, a e - b d)$ $(bf-ce, cd-af, ae-bd)$ . In this case the solution is $< - 1, - 28, - 16 >$ $<-1,-28,-16>$ .

Explanation:

$< 4, 5, - 9 > \times < 4, 1, - 2 >$ $<4,5,-9> xx <4,1,-2>$

= $< (5 . (- 2) - (- 9) .1, (- 9) .4 - 4 . (- 2), 4.1 - 5.4 >$ $<( 5.(-2)-(-9).1, (-9).4-4.(-2), 4.1-5.4 >$

= $< - 1, - 28, - 16 >$ $<-1,-28,-16>$
