Question

please help me correct the following

Your answer is partially correct. d d Calculate [ri(t) r₂(t)] and[r₁(t) × r₂(t)] first by differentiating · dt dt the product directly and then by applying the formulas d dr2 dri [r₁(t) · r₂(t)] = r₁(t) · + r₂(t) and dt dt dt d dr₂ dri [r₁(t) × r₂(t)] = r₁(t) × + x r₂(t). dt dt dt r₁(t) = cos(t)i + sin(t)j + 5tk, r₂(t) = 4i + tk d [r₁(t) · r₂(t)] = = 10 t - 4 sin(t) dt d [r₁(t) × r₂(t)] = [(t cos(t) + sin(t)) i + (t cos(t) − cos(t) +20) j — 4 cos(t) k X dt .
