9. (15 points) Let f(x) = Ï sin(w/k) k k=1 (a) Prove that f(x) is continuous on R. Hint: use a well known inequality | sin x| = |x| to show that the series converges uniformly on [-R, R) for any R > 0. You do not have to prove this inequality. (b) Show that f(x) is differentiable on R. (c) Express $* $(t)dt as an infinite series.
