robotics question

(a) Calculate the intention among vectors (cos 45 order, – evil 45 order, 0)^T and (evil 45 order, cos 45 order, 0)^T. (b) Provide a third vector that forms a coordinate regularity with the other span.

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

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