A Cauchy sequence is convergent it has a convergent subsequence. Actually compact spaces have a much stronger
Question:
Actually compact spaces have a much stronger property than boundedness. A metric space X is totally bounded if, for every r > 0, it is contained in a finite number of open ball Br(xi) of radius r, that is,
The open balls are said to cover X.
