    I'm doing AS Maths and Further right now on Edexcel with the modules: c1 , c2, fp1, d1, m1 and m2. I've just realised that the spec says that I need c3 knowledge. Four chapters in and I've only noticed some c3 trigonometry being used in one example. Should I start learning c3?

    Thanks in advance.

    Having just finished learning the M2 course, you don't really need to know C3 stuff, there is a tiny bit of c3 trig identities so maybe just learn that bit. But it mainly builds on M1 and uses a little bit of C2 too.

    Only a few trigonometric identities, such as the sec2x = 1 + tan2x one - if any C3 comes up, it is most likely that this identity will be involved. Differentiation has been required in the book, although it has never showed up in past papers but they could always decide to catch Y12ers out with it.

    C4 vectors has also helped me tons with a few papers.

    Nope, I got an A* in M2 last year, before I had ever even thought about picking up a C3 textbook. Don't waste your time lmao

    Tricky one... It wouldn't do any harm learning the extra stuff I suppose. Although it's doubtful that you'll come across the Rcos(x+a) saga in the M2 exams, but if you feel that it will boost your confidence with the trig involved in resolving vectors etc then I say go for it
