Expert Answer:

Let the two vectors be A and B

A = Ax i + Ay j + Az k

and B = Bx i + By j + Bz k

R1 = i .... the position vector for point (1, 0, 0)

R2 = k .... the position vector for point (0, 0, 1)

A.R1 = AR1cos45 = Ax

1/2 = A.........Since A = 1, vector of unit length.

A = 1/2 or (1/2, 0 , 0)

Similarly,

B = 1/2 k or (0 , 0, 1/2)
