Final Exam R 5/7
1:00-4:00pm
Fowler 307
Final exam will cover all HWs, with emphasis as follows:
Most emphasis: Ch 19 and 20 (HWs 25-30).
Least emphasis: Ch 13, 15, and Sec 14.6, 14.7 (the concepts in chapter 13 are fundamental and used a lot in other chapters; but I won't emphasize homework problems from Ch 13).
Medium emphasis: all other sections that we covered, plus the "proofs" (or explanations) mentioned in HWs 5 & 9.

As with midterms, final exam problems will mostly be based on homework problems and will mostly be straightforward.

This homework assignment is long. These two sections are introductory and hopefully you won't have a hard time with them.
Future assignments will be shorter.
