In chapter 4, we covered 4.1-4.4. You definitely should know the definitions of the following terms: open set limit point isolated point closed set closure of a set compact set bounded set open cover finite subcover The Cantor set lim x c f ( x ) = L continuous at a point c continuous on a set A bounded function on a set B Also know the following theorems: The union of open sets is open and the finite intersection of open sets is open The Density of Q in R (Theorem 3.2.10) The closure of A is closed (Theorem 3.2.12) Complements of open sets are closed and complements of closed sets are open Heine-Borel Theorem

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
