- To Know: I have posted another proof quiz due Monday. It’ll be about the definitions of injective/surjective. The text has examples, and we did examples in class, but here’s two more from YouTube: surjective and injective.
- To Know: I’ll soon (over the weekend) be posting a video solution to Quiz 6, whose scores were released.
- To Do: Optionally: Watch the YouTube videos above giving an injective and surjective proof example, in preparation for the quiz.
- To Do: Read Chapter 12.4 (Composition) and do Exercises 1-8 to hand in.
