- Finish up what you can of the worksheet from class today. You’ll find the worksheet online including a hint sheet — with that you should be able to make further progress. This is the topic of Pigeonhole Principle and I will now assume you can use this as a proof method (in simpler circumstances). Some examples with worked solutions can be found in Hammack, Section 12.3.
- Badges on Friday will now include all Logic badges. There’s one we haven’t discussed yet: Converse and Contrapositive. This is a quick one, and I’ll discuss it briefly in class, but you can also look this up in your book. The quiz will also include Sets badges for the second-to-last time, so please study any of those that you are missing.
