If ` vec a` and ` vec b` are two non-collinear unit vectors such that `| vec a+ vec b|=sqrt(3),` find `(2 vec a-5 vec b)dot(3 vec a+ vec b)` .

If vec a and vec b are two non collinear unit vectors such that |vec a+vec b|=3, find (2vec a-5vec b)3vec a+vec b

If vec a and vec b are two non collinerar unit vectors and if | vec a+ vec b | = sqrt 3 , then find the value of (vec a-vec b). (2 vec a+ vec b) .

If vec a and vec b are non-collinear unit vectors and |vec a+vec b|=sqrt(3) then (2vec a+5vec b)*(3vec a-vec b)=

vec a and vec b are two non-collinear unit vectors vec a,vec b,xvec a-yvec b form a triangle.

If vec a, and vec b be two non-collinear unit vector such that vec a xx(vec a xxvec b)=(1)/(2)vec b, then find the angle between vec a, and vec b

If vec a,vec b are two unit vectors such that |vec a+vec b|=2sqrt(3) ,then the angle b

12. If vec a&vec b, are unit vectors such that vec lvec a-vec b|=sqrt(3), then find |vec a+vec b|

Let vec a and vec b be unit vectors such that |vec a+vec b|=sqrt(3). Then find the value of (2vec a+5vec b)*(3vec a+vec b+vec a xxvec b)

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

If |vec a|=1=|vec b| and |vec a + vec b|=sqrt3 then evaluate (2 vec a - vec b) * (3 vec a + vec b) .
