Question
Transcribed Image Text:Given a metric space.
<X,p>
(a) If the sequence (n)neN CX is convergent, show that it is bounded.
(b) If the sequence (Tn)neN C X is convergent, prove that it is Cauchy. Is the converse true?
Justify your answer.
(c) True or false? Justify your answer. If (n)neN is a bounded sequence in X, then it has a
convergent subsequence.
(d) Given two sequences (zn)neN, (n)nEN C X. Suppose that they converge to the same
limit a € X. Show that the metric distance p(x, yn) → 0 as noo? Is it true that
if p(xn, Yn) → 0 as noo, then the two sequences have the same limit? Justify your
answer.
