Problem 2: Differentiate the following. They use a combination of chain, product and quotient rules. You do need not simplify your answer fully for these questions. (a) 9 (t) = 33 cos (i) 1+2s {b} NU=m (c) h(a)=2::/E (d) f (a) = (x2 + 1 3 72 - 1 (e) y = V1 + tan (t) (f) G(y) = - (y - 1)4 ( y2 + 2y) 5
