The prerequisites for this course are listed
in appendix C
. You should look over this appendix, and
make sure that everything in it is more or less familiar to you.
If you are unfamiliar with much of this material, you might want
to discuss with your instructor whether you are prepared to take the course.
It will be helpful to have studied some trigonometry, but all of
the trigonometry used in these notes will be developed as it
is needed.
You should read these notes carefully and critically. There are
quite a few cases where I have tried to trick you by
giving proofs that use unjustified assumptions. In these
cases I point out that there is an error after the proof
is complete, and either give a new proof, or add some hypotheses
to the statement of the theorem. If there is something in a proof
that you do not understand, there is a good chance that the proof
is wrong.
