Read your text, pages 75-77, Proposition 3.5 and Problem 3.6 on page 82. Beyond that, read as you see fit; you will be reading ahead, which can be excellent.
I will shortly post homework for next week and some information on next week’s Quiz #2.
If you missed Wednesday and/or Friday’s classes, obtain class notes covering the material that isn’t in your text. See Lectures page (above, right) to find out what that is.
