Section 9.2.
Section 9.3.
Section 9.4.

**Previous Exam Problems:** TBA.

All of these problems (or versions of them) were given as 21-122 exam
problems in a previous semester. (Actually they were give as problems in
21-117, when 21-122 was taught as two separate mini courses, 21-117 and
21-118. Anyway, they should give you a good idea of the type of problem I'll
be likely to write the exam.)
Here is the reference table you will be
given to use during the exam. It's the same as for the last exam, and there is
probably a lot of stuff you won't need, but the trig identities could be
helpful.
