Today:
- Announcements:
- Last time we took a look at two problems:
- #14 -- showing that the intervals centered at a rational
with rational width are countable
- #17 -- showing that an open cover can be replaced by a
countable subcover (an arbitrary union of open sets --
which is open, remember -- can be replaced by a
countable "subunion").
- Today we begin chapter 4, section 4.1 on
limits and continuity.
