    Did people get 4 for the propotionality constant
    i got 1/4

    because 1/2+x + 1/2-x = 4/(2+x)(2-x)

    but when integrating the differential equation you have intergal 1/(2-x)(2+x) dx which means you have to divide by 4 so you get an equation like likes 1/4 * (4/(2+x)(2-x)) which you can intergrate it as 1/4 Integral 1/(2+x) + 1/(2-x) dx

    If you worked AG again in later parts. You should've got them right. if you used the same values, you may lose the A marks and should get the rest.

    Any idea for grad boundaries?
    I needed 85/100 ums in that paper for A* overall.

    Some numbers i saved on my calculator:

    0.811 (think this might of been K in last question?)
    16/3
    26.565
    56.04 (the angle?)
    5sqrt(2) (length?)

    and for the comprehension:

    104.5m
    11.35 degrees

    Guys what did you do for the last 4 marker on the comp about percentages.

    Since it said 'about right' I just classed the 70 and 80 together then went on through there.

    Some answers I got

    1)Root10cos(theta+1.249)
    Invalid because4/root10 is bigger than 1
    2)P=2,Q=-2
    3)Theta=90,26.565
    4)volume=16Pie/3
    6)Area was 8
    7)Length 5root2
    -Q(12/5,8/5,2)
    Ratio 3:2
    8)Constant of proportionality was 1/4
    and k=0.811

    Not sure about any others? They were mainly show thats werent they?

    How many marks do you think you need to get for average 90 ums. I did fine on c3, c4 papers but messed up the comprehension so badly. I wouldn't be surprised if I got half marks on it.
