Okay, now I need anybody who can help me with one of these problems. I have a trigonometry test coming up soon, and I don't know how to solve these problems on my review. So, if anyone can show me how to do at least one or all of these three problems, it would be greatly appreciated. Here they are:
1. tan x sin x
---------- - ----------------- = sec x + cos x
csc x - cot x csc x + cot x
2. tan^3 x + sin x sec x - sin x cos x
------------------------------------------- = sin x + tan x sec x
sec x - cos x
3. cos x - cos 2x x
------------------- = tan -----
sin x + sin2x 2
If anyone can give me some kind of advice, or at least a good explanation, ten points will be guaranteed.
