First off I have a crummy textbook that doesn't do a good job of expaining Trig., if I did have a good one I would read it before I posted so many questions, but needless to say I don't.

For tests and future references I want to know how to solve problems when you are given a Sin(2x), Cos(2x), Tan(2x), CSC(2x), Sec(2x), Cot(2x). The problems are really easy for me when there is just Sin(x), Cos(x), Tan(x), CSC(x), Sec(x), Cot(x). If you take a look at this post Soroban created he did a real nice job of of putting each in terms of (opp)^2+ (adj)^2= (Hyp)^2. I really had never though of using Path Theorm this way. Here is the post is there any you can corollate his reasoning with this problem?
