Given the following subsets of R:
A = R\Q = {x ∈ R|x not in Q}
B = {1, 2, 3, 4}
C = (0, 1]
D = (0, 1] ∪ [2, 3) ∪ (4, 5] ∪ [6, 7] ∪ {8}
(a) Find the set of limit points for each subset when considered
as subsets of RU (usual topology on R).
(b) Find the set of limit points for each subset when considered
as subsets of RRR (right-ray topology on...
