Let v(t) = (5t2, - t,4) and g(t) = 2vt. Compute the derivative of the following function. v(g(t)) d (v(g(t))) = . t=7: \fit Find a tangent vector at t= E for the following parameterized curve. r(t) = (3t, cos 4t,7 sin t) Choose the correct answer below. {:3 A. (3,010) 311: B. .0.7> {:3 C. (3:4: ' 7) (3;. D. Since r'(t) = 0, there is no tangent vector
