    My maths teacher said have it`s setting on DEG, I think for the
    "SIN, COS, TAN" Questions

    Sin = O over H
    Cos = A over H
    Tan = O over A.
    "Oh, hell, another, hour, of, Algebra"

    Best of luck guys!:o

    Put it on normal and deg


  • Registered Users, Registered Users 2 Posts: 6,840 ✭✭✭Luno


    Put it on normal and deg

    You can only do one or the other! :O I'll keep it on deg and see how things go...

    I'm going through a paper one exam, anyone know how to do this question? :confused:

    "Write 44100 as a product of its prime factors"


  • Registered Users, Registered Users 2 Posts: 9,553 ✭✭✭soccymonster


    I'm really nervous about paper 1 (well for my sister!). I helped her with paper1 for an hour last night but she finds some of the questions like indices and surds very difficult in contrast to paper2. :( i'll be holdig the Rosary beads for the next few hours anyways.

    Oh and don't do what I did and notice 15mins before the exam ends that your calculator is on radians :o

    You're such a good sister. :eek:

    My brother & sister don't even know what exams I have today :pac:


  • Registered Users, Registered Users 2 Posts: 6,840 ✭✭✭Luno


    I helped my brother who is doing his leaving cert with his maths yesterday! :pac:


  • Registered Users, Registered Users 2 Posts: 9,553 ✭✭✭soccymonster


    Well, of course I don't want her to fail! :) But I love helping her out because it gives me a somewhat invincible power over her. I'm like the master training her. I love JC maths too :P (yet sadly, I can't answer that exam question DKZ, apologies).


  • Closed Accounts Posts: 2,347 ✭✭✭Closed ac


    I've figured it out.

    You have to divide it by prime numbers.

    You just do it like this
    44100/ 2
    22050/ 2
    11025/ 5 (cannot be divided evenly by 2 anymore)
    2205/ 5
    441/ 3
    147/ 3
    49/ 7
    7 so the prime factors are 2,2,3,3,5,5,7,7 :D

  • Registered Users, Registered Users 2 Posts: 2,218 ✭✭✭padocon


    Good luck! I'm finished


  • Registered Users, Registered Users 2 Posts: 9,553 ✭✭✭soccymonster


    How was it? :)


  • Closed Accounts Posts: 2,014 ✭✭✭Colm!


    I left higher maths p1 twenty minutes ago, it was really easy, one tricky question and I think I got that on the reattempt.


  • Registered Users, Registered Users 2 Posts: 1,171 ✭✭✭kevin12345


    Easiest maths paper ever :D what bit did you find difficult Colm


  • Registered Users, Registered Users 2 Posts: 2,457 ✭✭✭giggsy664


    Very simple. Q3 C ii threw me off though. Was fortunate a fiend of mine told me he brought a spare calculator as mine died about20 minutes into the exam D:

    For 3Cii, it said give it as a±b√b where a,b Are natural numbers (Positive whole numbers). Using the -b±b^2 formula, I got -1±3√3

    I got -1+1√7 ? I'm most likely wrong :rolleyes:
