1. Find the boundary and the interior for the following sets. Find the set of all accumulation points and the closure for the following sets. Classify each set as open, closed, or neither closed nor open. Use Heine-Borel theorem to determine whether it is a compact subset of R. A is closed/ open / neither closed nor open A is compact /not compact intB B is closed / open / neither closed nor open B is compact / not compact...

plz use the definition solve the question
Definition 1. Given a set A CR, an elementu ER is an interior point of A if there exists an e > 0 such that (x - 5,3 +E) CA. The interior of A is the set Aº consisting of all interior points of A. A set A is called open if A= A'. Definition 2. Given a set A CR, an element X ER is a limit point of A if for...
