5. Suppose fn converges to uniformly to f on [0, 1), all of the fn and f are differentiable with continuous derivatives, and that fh converges uniformly to g. Show that f' = g. HINT: The Fundamental Theorem of Calculus says that f(x) = S f'(t)dt + f(0). 6. Let ƒ be a continuous function on a compact metric space X and form the subalgebra A = span{1, f, f², f³,.. .., f",...} in C(X). Using Stone's theorem, show that A is dense in C(X) if ƒ is injective.
