Step-by-step explanation:

Find the direction cosines of the vector a and hence prove that, ... η unit vector perpendicular to both a & b , then, a X b = | a | | b | η Sinθ a θ η b ... ( i ) a x b ( ii ) | a x b | ( iii ) sinθ where θ is the angle between a & b ... ( a + b ) ○ {( b x c ) + ( b x a ) + 0 + ( c x a ) } ... ( a x b ) + ( a x c ) + ( b x c ) + ( b x a ) + ( c x a ) + ( c x b ).
