Math 251 (Phillips) Week 2 schedule and information

Monday 13 January:
- Worksheet used in class (corrected version).
- Solutions to the worksheet used in class (corrected version).
- WeBWorK assignment due, 9:00 pm. (The link depends on your class time.) Problems 1--5 are review. (You shouldn't need calculator or book graphs for Problems 1--4: you should recognize the graphs just by inspection.) Problem 6 is another version of the example used on Monday's worksheet. Problems 7 and 8 are based on the graphical description of limits from this week. Problem 9 asks you to guess limits based on either calculation of nearby values (like we did on Monday's worksheet) or from a graph. Don't use Google for calculation (I didn't write the problem); Wolfram Alpha is better (but requires cookies and javascript). Problems 10--14 use the limit methods 1 and 2 written on the side board, and Problems 15 and 16 use limit laws.
Tuesday 14 January:

- Difference file showing changes from the version handed out in class. Additions to the old version are in blue and wiggly underlined, and deletions from the old version are in red strikeout type.
