    Yes I put 60 degrees and 240 degrees instead of in radians, how many marks will I lose ?
    Probably just 1

    10cm, 5.4 something? for first
    two was 3pi/10 and radius 20.4cm
    third question was expanding (3+kx)^3 then k in part 2 was +/-1/root3 i believe

    four was logs logbase 3 (x^2/x+4)
    then x=12 i think
    five was integration dont remmeber values
    5bii was 4
    6 k was 91, n was 38 cant remember part ii
    7 was x^2-4x+3 and roots -1 1 and 3
    and integrated it between 3 and 1 think answer was 512/15 or something
    8 was
    yes sounds like what i got too roughly

    No, A is 3/5 as the 5/3AX gives values

    i.e Sine(5/3X36) = Sine(60)

    So your A is 5/3 for application however the scale factor is 3/5

    A=3/5 whcih when applied goes to 5/3
    K- root3/2
    i said a was 3/5 but i used 3/5 throughout.... Would that lose me loads of marks?

    i think i got something like 38, i'm probably wrong
    That is right because you should get N to equal 36, but as that isnt > 1200, you have to carry on going up from N=36 until the answer is > 1200, which it was at N=38

    What did you say a was? 5/3 or 3/5?

    how many marks would you lose if you said it was a stretch parallel to the x axis but got the stretch value wrong?

    depending on what it's out of, maybe like 1/2 marks? what was the actual answer for the stretch one of 3^x-2?

    What was the constant question answer with the coefficient of x^2
    wasnt it like 9k^2 x^2 = 27x^2
    9k^2 = 27
    k^2 = 3
    k = + or - root 3? idk if this is correct, that's what i put

    Yeah sorry I wrote parallel to the x-axis which the MS accepts

    A = 3/5
    k= root3/2

    scale factor: 1/9 also (1 divided by 3 squared)

    N=38

    the remainder =0

    YOU GET 3 LINER FACTORS

    You integrate between -1 and 3

    Last question tan=root3
    so tan=pi/3x and 4pi/3x

    First Q distance is 10cm

    X FOR LOGS =3 AND -12 (OR VICE VERSA)
