WebIf y ∈ X , then we can choose a sequence (x i) ⊆ X with d(x i,y) < , and since this i converges to y in M, it is Cauchy in X. Thus by completeness it converges in X, and by the uniqueness of limits, y ∈ X. Therefore X ⊆ X, so X is closed. 2) First, we know that if a sequence converges to some limit L, every subsequence of that sequence Weba cluster-point of A. If the limit of f at x 0 exists then it is unique, ie: f has at most one limit at x 0. Proof: (1) Suppose that L 1 and L 2 are limits of f at x 0. We need to show that L 1 = L 2, ie: L 1 −L 2 = 0. (2) Let ε be any positive real number. Then by the fact that L 1 is a limit of f at x 0 there exists a δ 1 > 0 such that ...
