Trigonometry!

[FarAwaySS2]

I was wondering if anyone knows where to find heaps of questions on Trig double identities formulae like 1/tanx, sin2x=sinxcosx, etc. I feel like I need lots of practice in simplifying and proving such formulae.

Any help would be much appreciated! thanks.

The Essentials Book? That had more than enough work IMO. After you've done that, test papers would be your next best resource.

You can begin looking at first year university mathematics books and completing relevant questions from there; please note some formulae are not present in the VCE Specialist Mathematics curriculum. If not A+ Specialist Mathematics notes can also be of benefit to your endeavors or completing the textbook (Essential Specialist Mathematics of course) problems multiple times.
