Today:
- Announcements:
- Your assignment are returned:
- Several of you left entire problems blank, suggesting that
you didn't even know where to start (and evidently
either began your homework very late or were reluctant
to ask my about them -- if the latter, why?)
- You can work together -- I don't know if you are, but that
could certainly help jump start some of you.
- Some of you are relying on intuition, old calculus
results, etc. when attempting the problems -- rather
than the definitions and theorems we're encountering in
this class.
- There's lunch today!
- Today:
- Last time we wrapped up material from section 2.3, Bolzano-Weierstrass:
- introducing lim infs and lim sups.
- We proved half of Exercise 16, p. 59.
- Today we jump into section 3.1, the Topology of the Real numbers
- Unusual start: a graph of the definitions and theorems of
chapter 3.1.
- Homework: make such graphs for chapters 1 and 2. Make them
pretty!
