d Calculate r1(t) · r2(t)] and dt [ri(t) × r2(t)] first by differentiating dt the product directly and then by applying the formulas dr2 dri d [ri(t) r2(t)] = r1(t) · r2(t) and dt dt dt [ri(t) × r2(t)] = ri(t) × dt d dr2 dri x r2(t). dt r1(t) = 8ti + 2t²j+6t°k, _r2(t) = t*k [r:(t) · r2(t)] [ri(t) × r2(t)] = dt
