    afraid not...i got y=3x/2+1/2

    and for sum to 20 i got 87.8
    wow how do you rememmber allthe answers i cant remembe rmost of it!

    Yep i agree wiv u y=3x/2 +1/2

    and sum was 87.8

    On the stationary point was it max or min??

    Sounds about right to me, think my sum to infinity was 100 also.

    Yay think i did quite well, the general concensuss of results i got the same as except for the inequalities question which i messed up.
    Excellent, so that is hopefully an A on P1 and a nice shiny E on P3

    question 1a was the midpoint, (5,3) or somthing like that.

    1b) y=1.5x + 0.5

    2)17 - 12 root 2
    b) 0.5 + 0.25 root 2

    3) the football pitch thing:

    a) x>65

    B) x sqaured + 20x - 4800 < 0
    (x + 80) (x - 60) < 0

    end up with the solutions being +ve when x<-80 and x>60

    final ans: 60<x<65


    4) tan x = 8/3

    b) there were 2 answers, cannot remember.....

    c) 70.5 and 289.5

    5)



    6) this is the +/- SQR3 1.....by substitution or proving x =.........

    7) Q: (3, 12)

    prove it is parallel by........ :confused:

    area = 4/3




    are these all correct then? ( i cannot memba all the ?'s!)

    looks like it!

    Yeah, 2slick, those look right to me. To prove PQ is parallel to the x-axis, just show that the gradient is zero, so the equation of the line is y=12.

    If I remember correctly, it was minimum.

    Yes because the change in gradient was a posive number.

    Yeah it was the midpoint of the two points (1,2) and (5,8) and then the equation of the line passing through those two points.

    If its a really hard paper then the marks are scaled up. In practice this means the grade boundaries are lower.

    If its a really easy paper then the marks are scaled down. In practice this means the grade boundaries are higher.

    would people agree if i said, after most people opinions on the exams the grade boundaries will be

    A 64/75 UMS 80
    B 57/75 UMS 70
    C 49/75 UMS 60
    D 41/75 UMS 50
    E 34/75 UMS 40

    this looks ok but im wondering whether a would be 85 ums or something because of this paper being easy - i hope not

    no 80 UMS is always an A in every paper every subject (if its out of 100 that is)

    oh yea soz ofcourse, i meant 85% not the ums

    I found it good, i got mostly what yu guys got.
    But for the inequalities quesiton i got 60<x<65 AND x<-80, because the left hande side of the quadratic had to be taken into account as well.

    Also from where r yu getting this information that 67 is the grade boundry from last year? i looked at the p1 examiners report (available on edexcel site for june 03) and it said mean mark 47.-something, and standard deviation 21.-something,
    that means that the top 5% of the entry got 68 and above meaning that the grade A boundry (should be 80% of the entry) would have probably got around 60/61 to get an A
    Last year i got 60/75 for P1.....this gave me 73 ums(on my AS results sheet) ie a low B. So nope, 60/61 did NOT give you an A.

    wow 80% and you only got a low B. how do you know you got 60/75?
