If `vec C=vec A+vec B` then

If three vectors vec A, vec B and vec C are such that vec A .vec B =vec A .vec C , vec A xx vec B = vec A xx vec C , vec A!= vec 0 then prove that vec B =vec C .

If vec A+vec B=vec C , then magnitude of vec B is vec C-vec A sqrt(vec C*vec A-vec B*vec A) sqrt(vec C*vec B-vec A*vec B) C-A

If vec a=mvec b+vec c. The scalar m is (vec c*vec b-vec a*vec c)/(a^(2)) (vec c*vec a-vec b*vec c)/(c^(2)) (vec a*vec b-vec b*vec c)/(b^(2)) (vec a-vec c)/(vec b)

If [vec avec bvec c]=2, then find the value of [(vec a+2vec b-vec c)(vec a-vec b)(vec a-vec b-vec c)]

If vec a, vec b and vec c are non coplaner vectors such that vec b xxvec c = vec a, vec c xxvec a = vec b and vec a xxvec b = vec c then | vec a + vec b + vec c | =

The two vectors vec(A) and vec(B) are drawn from a common point and vec(C)=vec(A)+vec(B) then angle between vec(A) and vec(B) is

If vec a is a non-zero vector and vec a * vec b = vec a * vec c, vec a xxvec b = vec a xxvec c, then

If vec a,vec b and vec c be any three vectors then show that vec a+(vec b+vec c)=(vec a+vec b)+vec c

Let vec(C )= vec(A)+vec(B) then

If vec a, vec b, vec c are three vectors such that | vec b | = | vec c | then {(vec a + vec b) xx (vec a + vec c)} xx {(vec b xxvec c)} * (vec b + vec c) =
