C3 trig

Hi, I was wondering if anyone had a document with all the proofs on it for the identities in chapter 6 and 7 in the edexcel C3 book

Thanks!

Ahh Edexcel. What I definitely remember from A-level is that the only proofs in C3 are of trig identities, i.e showing that the LHS=RHS using the results given in the course, such as the double angle formulae etc.

Or is your interest in non-examinable stuff?
