Calculate tri(t) - ra(t)) and ära(t) x rz(t) first by differentiating d d [r2ri) dt dt the product directly and then by applying the formulas d dr2 dr [ri(t). r2(t)] = ri(t). + r2(t) and dt dt dt d dr2 dr diri(t) x r2(t)] = rı(t) * [tt)] + x r2(t). dt dt dt ri(t) = cos(t)i + sin(t)j + 2tkr2(t) = i + tk () = [ri(t) · r2(t)) = dt d [ri(t) x r2(t)) = dt ) x (t) -
