So here is a picture of someone to
blame for this topic besides Coach Weedon. Hipparchus did not build trig
tables or know of such things and was more concerned with finding lengths
of chords of circles of a given radius with a given central angle. We will
talk of that kind of thing later, much later in fact.
Our main concern is to provide a course to
allow a review of most of your high school math and cover the main topics
of trig. If you have not done well in mathematics up to now, be of good
cheer. Now can be your time to change that and pick up some of the ideas
you may have had trouble with earlier. If you choose to work at it, you
can raise your previous average 1 or 2 levels. There are many
tests to help your average, and homework provides an easy way to increase
your average. Look carefully at the rules section in the subsequent pages
to see the details of calculating your grade. Hopefully, you will
agree that the system is built for you to be successful.
So set your goals today. Whether it's "C's for the first time"
or "exam exemption,"
Hipparchus will be proud.
