Let `vec a, vec b` and `vec c` be there unit vectors such that `vec a xx (vec b xx vec c)=(sqrt3)/2(vec b + vec c)`. If `vec b` is not parallel to `vec e`, then the angle between `vec a` & `vec b` is:

Let vec a,vec b and vec c be there unit vectors such that vec a xx(vec b xxvec c)=(sqrt(3))/(2)(vec b+vec c)* If vec b is not parallel to vec e, then the angle between vec a o*vec b is:

If vec a,vec b,vec c are three unit vectors such that vec a xx(vec b xxvec c)=(1)/(2)(vec b+vec c). If the vectors vec b and vec c are non-parallel,then the angle between vec a and vec b is

If vec a,vec b, and vec c are non-coplanar unit vectors such that vec a xx(vec b xxvec c)=(vec b+vec c)/(sqrt(2)),vec b and vec c are non parallel,then prove that the angel between vec a and vec b is 3 pi/4

If vec a,vec b,vec c are 3 unit vectors such that vec a xx(vec b xxvec c)=(vec b)/(2) then (vec b and vec c being non parallel).(a)angle between vec a&vec b is (pi)/(3) (b)angle between vec a and vec c is (pi)/(3)( c)angle between vec a and vec b is (pi)/(2) (d)angle between vec a and vec c is (pi)/(2)

Let vec a, vec b, vec c be three vectors from vec a xx (vec b xxvec c) = (vec a xxvec b) xxvec c, if

If vec a,vec b, and vec c are three vectors such that vec a xxvec b=vec c,vec b xxvec c=vec a,vec c xxvec a=vec b then prove that |vec a|=|vec b|=|vec c|

Let vec a and vec b be two unit vectors such that |vec a+vec b|=sqrt(3) if vec c=vec a+2vec b+3(vec aXvec b) then 2|vec c| is equal to
