Let fr: A → R be a sequence of functions with the property that for every ɛ > 0 there is an N such that k 2 N implies |fx (x) – f(x)| < e for all x € A. Then we say that fr converges uniformly to f. Prove: Let fr:A → R be a sequence of functions. Then fr converges uniformly iff for every ɛ > 0 there is an N such that l, k > N implies fr (x) – f;(x) < e for all x E A.
