Day 12, Mat420: Real Analysis

Today:

Announcements:
- Return of your second assignment. We'll look at a few of those.
- You can also fix those which are broken for half of the missing credit. Turn those in Wednesday (make a copy for yourself if you want to use them to study for the exam).
- We do have a test coming up, this Friday. It will be over chapter 1 only. FYI: you will be expected to reproduce the proof of one theorem (or part of theorem) that is given in the book, so review those proofs for any that have stumbling blocks (and ask next week!).
  There will also be a take-home portion.
- Last time:
  - Proof of Theorem 1-15
  - Proof of Theorem 1-16 -- contraposition versus contradiction
Today:
- Let's start with Mandy's use of contraposition to prove a result from her last homework.
- Let's take a look at a few of those homework problems:
  - #4 - section 1.2 (Jennifer, Justin, Mandy)
  - #4 - section 1.3 (Amber)
  - #14 - section 1.3
- Sequences of Real Numbers
  - Overview
  - Let's look at some of the problems from the exercises (1-4, 6, 14).
