u = a - b, v = a + b, |a| = |b| = `implies |u xx v|` =

vec u = vec a-vec b, vec v = vec a + vec b and | vec a | = | vec b | = 2 then | vec u xxvec v | is equal to

If vec(u)= vec(a)- vec(b), vec(v)= vec(a) + vec(b) and |vec(a)| =|vec(b)|=2 , then |vec(u) xx vec(v)| =

Let V = {a , e , i , o, u} and B = {a , i , k , u} . Find V - B a n d B - V

Let vec a and vec b be two non-collinear unit vector.If vec u=vec a-(vec a*vec b)vec b and vec v=vec a xxvec b, then |vec v| is |vec u| b.|vec u|+|vec u*vec a|c.|vec u|+|vec u*vec b|d|vec u|+widehat u.|vec a+vec b|

Let V = { a, e, i, o, u } and B = { a, i, k, u} . Find V – B and B – V
