    People are saying they got pi/6 for 9ii but I got 0.6.. something. Anyone else?

    my thoughts are that it is fair paper I just unfortunately messed up q6 so probably dropped about 5 on that and on q9 the final part I got something different from 32sin(theta) somehow and previous part I dropped a mark or so.

    Hopefully core four goes better!

    1 y=12x=15

    2 4x-4Inx-1/x

    3 1/13 and 3/4

    4 (i) Show that
    (ii) 5/2

    5 a=6 b=5

    6(i) Sketch
    (ii) 0.242
    (iii) x= 0.242 and y=-0.133

    7(i) any real values of g(x) and f(x) is greater and equal to 3
    (ii) f is not a one to one function inverse function of g(x) is x+4a/5
    (iii) x= 3a/2 and -5a/2

    8(i) Show that
    (ii) 4+2root 2
    (iii) only pie/6
    (iv) 32 sin

    Any guess for the grade boundaries for an A*?
    What about the equations of the reflected curves? I got 1.33 for some reason for y coordinate?

    A* will be 63-64+

    Ugh I didn't do so well, now I'm praying for the grade boundary to be low and do better in C4 to get an A*

    Actually yeah I think that's what I got. How many marks was that question?

    I think they are exactly the same

    for tan(A-B) how do you get 1/13 and 3/4?

    I didn't get pi/6 or whatever. Pretty sure it was just 4 + 2root 2

    Yeah I remember getting 0.6 something too.
    If the question asked for an exact value that's so silly of me x(

    3, ended up being cos2theta =0.25

    What did people get for Tan A and Tan B? I managed to get Tan A as 4 and -3 and Tan B as 27 which I'm guessing is wrong

    Can anyone help me with what i can do about this? I sat my C3 exam this morning and was given a seat that was much higher than my table(sounds stupid so far, i know) but as someone who has suffered from light occasional back pain for a few years, this caused s much discomfort that i was in serious pain throughout the entire exam (and that was with painkillers) does anyone know if there is anything i can do about this?
    Too late now. If you wanted to you could've asked an invigilator to stop and you could've spoken to them about having a break, new chair, etc.

    You didn't say anything though so it's too late now I think.

    Tan^3B was 27 so TanB was 3.

    because of the reflection in y axis and x axis

    Originally, the x and y coordinates are both positive. After the transformation, they will become negative

    tan^3B was = 27 so tanB=3

    then use the trig identity formula
