This week in Adv. math we learned different sections in chapter eight. In section 8-4 you are pretty much just replacing all the identities with trig functions. All you have to do is memorize and follow your chart. This is definitely one of the easiest sections if you memorize all your functions.

STEPS:
1. Pythagorean identities
2. Move everything to sin and cosine OR tangent IF POSSIBLE
3. Algebra to simplify
4. identities again
5. Algebra again

Ex.
sin theta (csc theta - sin theta)
sin theta(1/sin theta - sin theta)
1 - sin squared theta
cos squared theta
