    How'd you do in your pre and stuff?

    Failed the DEB mock but then did a second one and went up to a B, so I should pass at least anyway. It just feels like I've forgotten a lot of what I learned.

    I was nominated....


    annnnd once again, to clarify, can only theorem 11, 12 and 13 be asked to be formally proved in question 6?

    I would say yes but I'm not 100% certain. 11, 12 and 13 are the only theorems in my revision book that have full proofs done out so I'd assume so. I'm more worried about the trig ones, don't know them at all.

    The syllabus says only 11, 12, 13 but all theorems are in my books... cant wait to open the exam and see PROVE PYTHA..... FFFFUUUUUUUUUU

    That proof is actually my favourite and the only one I can remember, so maybe I'd actually like that,

    Anyone have a list of what has to be learned/proofed/derived for paper 2?

    I have a sheet with:
    -Theorems 11, 12, 13
    - Derivations of certain trig formulae, 1-7, 8
    - Constructions 16-22
    - Statistics sample types
    - Geometry terms - axiom, corollary etc

    That it?

    I believe so, nothing else I can think of off the top of my head.

    is the sine and cosine rule proof included in thet trig formulae?
    You need to be able to prove sine rule by the areas of the triangle too, it came up one year.. really not too hard

    Oh only 16-22 for the constructions, that's not too bad I thought it was all of them.

    You're expected to know the rest of them from junior cert, they're piss anyways.

    Sorry to comment here as I am not a higher level maths student,just wondering will admissions be making a ordinary level paper two predictions thread..I am new to boards and don't know how to make a thread

    Looks like we have another volunteer :D

    Go to the Leaving Cert forum (where this and the OL Maths P1 thread are) and if you're on a phone/tablet click 'Post' to start a new thread. If you're on a computer, click 'New Thread'. Give it a title and a brief opening post and click 'Create'/'Submit'

    Edit: Looks like someone else already did. Here it is.

    Hopefully it will just as doable as paper 1 ,usually i find paper 2 to be easier,inferial statistics will most likely come up as it is new this year

    i actually found p1 tough :( section A i think i got maybe 110 or 120/150 but on section B it all depends on the attempt marks, could range from 50-120/150 :)

    right so apart from the theory what is the key stuff we should know?

    stats: mean,mode,median - Interquartile range - P-values- Hypothesis testing - P-values - mean/population proportion

    prob: expected value - hmm cant even think of the rest

    co-ordinate geometry: circle in terms of gfc - circle touch x/y axis - tangent from point off circle - common tangent between 2 circlew - points of intersection - angle of lines - dividing a line into segments

    geometry: translation - proving angles are similar - cyclic quadrilatereals

    trig: cosine rule - sine rule - sine/cos waves -

    what else is the key stuff?

    For Probability throw in:
    Mutually Exclusive
    AND/OR events
    Independence
    Arrangements
    Combinations
    Conditional Probability
    Bernoulli Trials
    z-scores

    know how to prove if events are independant or not, i.e is P(A).P(B)=P(AnB) or P(A|B)

    i really have to revise probability lol.

    Proof by contradiction is in book 1, but again, they don't HAVE TO constrict book 1 material to paper 1..... i've seen proof by contradiction on q6 as the proof so yeah, it could come up

    Could a formal proof of any of the theorems other than 11,12 & 13 come up? (like on one of the mocks - exam craft I think?)

    I did bad in paper 1 as i wasn't expecting those stuff to come up.. What are people predicting in paper 2? i saw the predictions on this forum were very accurate. I need about 200 points to pass Higher level maths. So does anyone have any ideas what will come up? Thanks :)

    Hypothesis testing will probably make an appearance. Have a look at the 2015 sample papers, they're likely to be indicative of the type of question that will come up. You can find them here - www.themathstutor.ie/official-marking-schemes.html

    Along with that I'd expect bernoulli triads in probability. Hopefully there'll be a theorem and construction too.

    I dont understand the new sampling stuff at all, why don't we use 1/rootn anymore? why is it 1.96sigma/rootn now? :l and wtf is p(1-p) or whatever.. oh god im so ****ed if this comes up lol.

    Do you have to be able to derive all 24 trig formulae or what number is it up too

    You have to be able to derive the following 1 to 7 and 9.

    8 altogether.
