If `vec a, vec b` and `vec c` are non-coplanar vector and `vec a times vec c` is perpendicular to `vec a times(vec b times vec c)` ,then the value of `[vec a times(vec b times vec c)]times vec c` is equal to :

If vec a,quad vec b and vec c are non coplanar vectors and vec a xxvec c is perpendicular to vec a xx(vec b xxvec c) then the value of [a xx(vec b xxvec c)]xxvec c is equal to [vec avec bvec b] b.2[vec a xxvec c)]xxvec b c.vec 0 d.[vec avec bvec c]vec a

vec a, vec b, vec c are non-coplanar vectors, express vec a xx (vec b xxvec c) as a linear combination of vec a, vec b, vec c

Let vec a,vec b,vec c are three non-zero vectors and vec b is neither perpendicular to vec a nor to vec c and " (vec a timesvec b)timesvec c=vec a times(vec b timesvec c) .Then the angle between vec a and vec c is:

Solve the following equation for the vector vec p; vec p xx vec a+(vec p. vec b)vec c=vec b xx vec c where vec a ,vec b,vec c are non zero non coplanar vectors and vec a is neither perpendicular to vec b non to vec c hence show that (vec p xx vec a+([vec a vec b vec c])/(vec a*vec c) vec c) is perpendicular vec b-vec c.

vec a, vec b, vec c, dare any four vectors then (vec a xxvec b) xx (vec c xxvec d) is a vector Perpendicular to vec a, vec b, vec c, vec d

If vec a,vec c,vec d are non-coplanar vectors,then vec d*{vec a xx[vec b xx(vec c xxvec d)]} is equal to

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)), then the angle between vec a and vec b is a.3 pi/4b. pi/4 c.pi/2d. pi

If [vec(a) vec(b) vec(c)]=4 then [vec(a)times vec(b) vec(b)times vec(c)vec(c) times vec(a)] =

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 three non-coplanar unit vector such that [vec(a),vec(b),vec(c)]=3 then [ vec(a) times vec(b), vec(b) times vec (c),vec(c) times vec(a) ] equals
