Theorem 8.4. A sequence of points in a metric space has at most one limit. Proof. We will show that a sequence of points in a metric space has at most one limit. We will do this by contradiction, by supposing that some sequence has two different limits, and deriving the contradiction 1<]. Suppose the sequence (Pk)'_, converges to two different limits a and b. Let ε = d (a,b). <This choice for ɛ will be explained by a calculation...
