tan x cos x ---------- + ------------- 1 - tan x sin x - cos x
If I am required to simplify and not prove as I don't know the answer to this equation, is there a standard way to commence simplifying the equation and is there a difined time to stop? Each part of the equation, tan x, cos x, 1 - tan x all can be changed which ones do you change and when do you stop. You can continually change and rearrange and then change again your new answer. I have trouble knowing where to stop if I don't have a defined identity to prove.
Hopefully you will be able to understand what I mean!
