| Trigonometic
Functions Sine, Cosine,
Tangent,Cotangent, Secant and Cosecant all rear their head in this section.
You learn what they are, what their graphs look like, in which quadrants
they are positive or negative, what reference angles are, what the unit circle
is, and how to find these functions' inverses. You will also learn
their equations and how they are all connected. Sound complicated?
Well, it can be at times. Thankfully, you can do some of the
work on your calculator and using your calculator is a great way to check
your answer. If you understood the last section, it will greatly help
with this section. Trigonometric Functions is a critical unit that
you must understand before you can really go on to the next two sections.
Otherwise, you will be up a creek without a paddle.
