Tues. Oct 17 
Section 3.5 #5, 7, 8, 9, 10a, 
Hint on 7a. Show that each of these open sets has a rational number in it and that these rational number are all different. Hence the number of such sets can’t be uncountable. Hint on 8a. Start with an open covering of T, extend this to an open cover of S (using the fact that T is closed) and then use the fact that S is compact to get a finite subcover (of S and then of T).
