For Wed:

• To Do:  Look over your Proof Quiz 7 and 8 and compare to Proof Quiz 7 Solutions and Proof Quiz 8 Solutions.  I’ve also posted a video solution for Proof Quiz 8 because I had some things to say about it.  Please watch the video (available on canvas).
• To Do:  Read Section 14.4 of your text.  This has the detailed proof that I only sketched in class today.  Do exercises 1 and 2 to hand in.
