If A is a compact subset of a metric space (X, d) and B is a closed subset of A, prove that B is also compact.
Is the following statement True or False? Justify each answer. If S is a closed bounded subset of a metric space X, then S is compact.
Let E1, E2, ..., En ⊂ X,d be compact subsets of a metric space X. Just using the definition of compactness, prove that E1 ⋃ E2, ⋃ ... ⋃ En, where n is a postive integer, is a compact subset of X.
