Web8 de out. de 2011 · Homework Equations. A function is uniformly continuous provided that whenever {u n } and {v n } are sequences in D such that lim (n→∞) [u n -v n] = 0, then lim (n→∞) [f (u n) - f (v n )] = 0. A function is bounded if there exists a real number M such that f (x) ≤ M for all x in D. Every bounded sequence has a convergent subsequence.
