    Hope there's constructions on Paper Two!


  • Registered Users, Registered Users 2 Posts: 40 LeavingCertee


    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.

    Anyone know how to find the mean value from a histogram?

    I agree.

    Are you sure?

    I remember it as 40 for Q7, 50 for Q8 and 60 for Q9.


  • Registered Users, Registered Users 2 Posts: 2,204 ✭✭✭Aspiring


    It was 40, 50, 60 I think.

    ya definatly was :(


  • Registered Users, Registered Users 2 Posts: 1,673 ✭✭✭aleatorio


    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?? :(


  • Registered Users, Registered Users 2 Posts: 192 ✭✭Isitthough?


    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.


  • Registered Users, Registered Users 2 Posts: 1,673 ✭✭✭aleatorio


    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!

    Is it constrctions 1-15 and 22, then theorems 11,12 and 13 we have to know for the exam? I am just so confused


  • Registered Users, Registered Users 2 Posts: 40 Joey!!


    Can anyone please tell me what theorems we have to know and constructions? I am soooooo confused


  • Registered Users, Registered Users 2 Posts: 1,673 ✭✭✭aleatorio


    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


  • Registered Users, Registered Users 2 Posts: 160 ✭✭plmko

    Theorems 11,12 and 13 in Geometry
    Trig theorems 1-7 & 9 in Trigonometry
    Constructions 1-22 in Constructions

    What book do you have, I'll tell you the pages?


  • Registered Users, Registered Users 2 Posts: 40 Joey!!


    Active maths, thank yo so much, i really appreciate it

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

    Theorems 11-13 are on pages 385&386
    Trig theorems are on pages 257,258,270 &271
    Constructions are pages 192-222
