Calculate a mira(t) r2(t)) and dale () d Calculate [ri(t) · r2(t)] and [ri(t) x r2(t)] first by differentiating dt dt the product directly and then by applying the formulas d dr2 dri [rı(t) • rz(t)] = rı(t). ri r2(t) and dt dt dt d dr2 dri [ri(t) x r2(t)] = ri(t) x + x r2(t). dt dt dt = + . = ri(t) = cos(t)i + sin(t)j + 2tk, r2(t) = i + tk d [ri(t) · r2(t)] t) · t ] = dt = d [rı(t) x r2(t)] dt =
