Tomorrow

[Kevin Lin]

Just a reminder that the 3rd homework set is due tomorrow at the beginning of class.

Also, we are having a quiz at the end of class tomorrow. It will cover induction and strong induction; even though I did not assign any homework from section 2.5, you should also be familiar with the material from that section that was covered in lecture. You should know, at the very least, the definition of countable and uncountable, and you should know how to prove that a set is countable in at least some simple examples. For example, you can try exercises 1, 2, 3, 4 from section 2.5.
