- Read through the administrative announcements from the last daily post. Topics include FCQs (please fill them out!), opportunities for grade improvement, etc.
- Class was recorded on Mon Apr 24 and is on canvas.
- The proof quiz will be a quiz about showing something is or is not injective/surjective/bijective. Review using Hammack, section 12.2.
- In class, I left one half of one proof unfinished. Please complete it. (See class notes.)
- Here are Pigeonhole Principle puzzle problems. Please work on them. The challenge is to find out what are the pigeons, what are the holes, which will lead you to a proof.
