Give Examples (this is complex analysis): (a.) First characterize open and closed sets in terms of their boundary points. Then give two examples of sets satisfying the given condition: one set that is bounded (meaning that there is some real number R > 0 such that |z| is greater than or equal to R for every z in S), and one that is not bounded. Give your answer in set builder notation. Finally, choose one of your two examples and...
