Find the value of: (vec j xxvec k) * (3vec i + 2vec j-vec k)

If vec a xx i+2vec a-4vec i-2vec j+vec k=0 then vec a=

(vec i + xvec j + 3vec k) xx (vec i-vec j + vec k) = 5vec i + xvec j-3vec k then x =

If a=vec i+4vec j,vec b=2vec i-3vec j and vec c=5vec i+9vec j then vec c=

If the vector vec a= x vec i + y vec j + 2 vec k is perpendicular to the vector vec b = vec i - vec j + vec k and the scalar product of vec a and vec c= vec i + 2 vec j is equal to 4 then x= ________ and y=__________.

Find lambda such that the scalar product of the vector vec i + vec j + vec k with the unit vector parallel to the sum of the vectors 2 vec i + 4 vec j - 5 vec k and lambda vec i + 2 vec j + 3 vec k is equal to 1.

Find the unit vector in the direction of the vector vec a + vec b if vec a =vec i +2 vec j + 3 vec k and vec b = 2 vec i + 3 vec j + 5 vec k .

The vectors of A,B,C and D are respectively 2 vec I + 3 vec j + 5 vec k, vec I + 2 vec j + 3 vec k, -5 vec I + 4 vec j - 2 vec k and vec I + 10 vec j + 10 vec k . Show tthat AB and CD are parallel.
