Evaluate the derivative ~ (tor(t)), where r(t) = (16,15, t). (Use symbolic notation and fractions where needed. Give your answer in the form (x(t), y(t), z(t)).) (19r(t ) ) =Let r(t) = (18, 16) g(t) = sin(7t) Evaluate the derivative using the Chain Rule. (Use symbolic notation and fractions where needed. Give your answer in the form (x(t), y(t)).) d at r(g(t)) =Calculate the derivative %r(g(r)) using the Chain Rule. r(t) =
