robotics question

(a) Calculate the direction among vectors (cos 45 limit, – ungodliness 45 limit, 0)^T and (ungodliness 45 limit, cos 45 limit, 0)^T. (b) Provide a third vector that forms a coordinate classification with the other span.

a)direction among 2 vectors=(cos 45 *ungodliness 45-sin45*cos45+0)/(1)*(1)=0

b)(0.i-0.j+1.k)
