I am asked to prove the following identities:
I think I should tackle the most complicated side as it is easier to aim for the easier looking side. (hope that makes sense )
I should warn you that I'm not good at this so please excuse my fumbling
I will attempt the RHS, cotθ-tanθ
so I'm stuck! Told you
I was aware of cotθ=1/tanθ=cosθ/sinθ
But I find this a mine field. And never know where to start nor which replacements to use. It's really confusing to me.(Headbang)
I would like to return to this a little later and ask you some questions about your thinking, if I may?
so the LHS has only one thing to play with. So I should tackle this side?
On the right track?
In my opinion, for b), tackle the left hand side by writing and use the addition formulae.

Thanks for that (Happy)
Your right - I should learn Latex, and will make an effort to do so after this weekend, which is this coming Monday. Promise Promise.
For anybody reading this who is interested, I just did a search on Latex video tutorials and came up with a couple of sites instantly. It seems there is a lot of help available online, as always.(Clapping)
TechScreencast - LaTeX Intro :: tutorial, videos, articles, screencast to learn technology"
YouTube - Tutorial LaTex
latex video tutorial rapidshare, megaupload, torrent download
Though I haven't looked closely at them, yet, I'm pretty certain they will be helpful and are reputable sites.
Is the last link ok?
