    Does anybody have a definitive list of proofs, constructions etc for HL Maths paper 2? So I know we have the 23 or so theorems/corollaries and the 3 constructions of ortho/circumcentre and incircle. And the trig proofs.. Is there much else?

    Does it matter if you leave out the calculator model? Completely forgot

    Just write it on your Paper Two and state that you used the same one for Paper One.

    Your superintendent should have checked, but maybe they didn't.

    No they didnt check or remind us. I was way too worried about the paper to even remember. Think il loose marks for paper one? I did show all the workings

    No you won't lose any marks because you will write the calculator number on Paper Two and the same person corrects both your papers.

    It's on the inside cover page. The instructions page to the left of the first question.

    Should be on the front page imo. It's that way for every other subject.

    What trig formulae do we have to derive...?
    We never did them in class :(
    In my book we have
    Cos2A+Sin2A=1
    The sine rule
    Cosine rule
    Compound angles (6 of them)

    Do I need to know them all off?? :(

    Hey you know the way we have 3 theorems on the coarse..well I was looking at the Ques 6's and I cant find them asking for the theorems anywhere there different.. Did they change them or do they change them every year?

    If you have the DEB mock on hand see Question 6A. That's exactly how Theorem 13 would come up I'd say.

    Just thought to point out, it says in the syllabus that either 6A or 6B will deal with theorems/constuctions :P

    Here's what it was like on the DEB mock for anybody that doesn't have it. Blanked out the answers so you can use it to practice on.

    Would you mind sending me that picture with the answers?
    I answered it in my mock and I didn't seem to get full marks for it and I'm not too sure why.
    Be great if you could, thanks!

    For anyone wondering about trig derivations, we can be asked to derive 1-7 and 9 on the list of trig eqns at the end of the syllabus

    Didn't think question 9 was the worst, 8 was more challenging was it not?
