Class
meeting
number
Date Text material for discussion Problem assignments, due the following class meeting
(9th ed’n numbers, if different, are bracketed [like so];
items now cancelled are struck through, thusly):
1 26 Jan Anton, Chapter 1, 1 & 2 None – first assignment to be announced in second class meeting
2 31 Jan Chapter 1, 3 & 4 & 5 1.1: ## 7, 8, 9, 12 [13], 13 [14];
1.2: ## 18, 27.
3 2 Feb Chapter 1, 5 & 6 & 7 1.3: ## 9, 12, 18, 19;

1.5: ## 12, 13, 15 (8th ed’n numbering)
or: ## 15, 16, 18 (9th ed’n numbering)
Note. Alas, the 8th and 9th editions diverge when it comes to Chapter 2: what was 1 in the 8th ed’n becomes the last of the 9th ed’n, while 4 of the 8th ed’n becomes 1 in the 9th. So we’ll attack this chapter by burning inwards from both ends, as best we can.
5 9 Feb 1st ½: Still winding up Chapter 1; 2nd ½: Chapter 2, 1, 2, & 4 1.3: ## 15, 16(c);
1.5: read text Example 4 and do ## 1, 2, 9 [10 in the 9th ed’n];
2.2: ## 1, 2, 3; and

2.4 [2.1 in the 9th ed’n]: ## 1, 2, 3;

2.2, ## 2-3 (8th & 9th ed’ns agree);
2.2, ## 16-18 (8th ed’n) or ##18-20 (9th ed’n);
