" If "|vec a|=4,|vec b|=2" and the angle between "vec a" and "vec b" is "pi/6," then "(vec a timesvec b)^(2)" is equal to "

if |vec a|=4,|vec b|=2 and the angle between vec a and vec b is (pi)/(6) then (vec a xxvec b)^(2) is equal to

If |vec a| =4 , |vec b | = 2 and angle between vec a and vec b is pi/6 , then (vec a xx vec b)^(2) is

IF vec x =vec a + vec b, vec y= vec a - vec b,|vec a|=2,|vec b|=3 and the angle between vec a and vec b is pi/3 then |vec x times vec y| is equal to

If |vec(a)| = 5, |vec(b)| = 6 and the angle between vec(a) and vec(b) is 60^(@) , then vec(a).vec(b) =

If angle between vec a and vec b is pi/3 then angle between vec a and -2vec b is:

If vec(a) is perpendicular to vec(b) and vec( c ),| vec(a) |=2, |vec(b)|=3,|vec(c )|=4 and angle between vec(b) and vec( c) is ( 2pi )/( 3) , then [ vec(a)"" vec( b) "" vec( c)] is equal to

Solve (vec a timesvec a)*vec b

If |vec(a)| = sqrt(3), |vec(b)| = 2 and angle between vec(a) and vec(b) is 60^(@) , find vec(a).vec(b) .
