Which one of the following gives the derivative of the vector function r(t) = e−³ti + cos(t²)j + sin²(3t)k? Select one: ○(t) = 7 -3e-³t — sin tj + 6 sin(3t) cos(3t - ○7 (t) = -3e-³¹7 - 2t sin(t²)j + 6 sin(3t) c ○ 7¹ (t) = −3e-³¹ - 2t sin(t²)j + 2 sin(t) co: ○7 (t) = 3e³¹7 – 2t sin(t²)j + 2 sin(t) cos(t) - None of the others.
