    ah right thank you, had a complete panic in the last minute when checking and had to re-do the question :mad:
    Why did you have it in square route form anyway, you just needed to find the difference in the y coordinates?

    didn't you have to find the length of the line? i can't remember what question this was, was 9 or 10.

    If you get over 90% in all a2 modules, yeah I think you can
    Your AS Grade doesn't matter when it comes to getting an A* at A2 providing you get above 210 UMS (B) out of the AS.. But you need to average 90% (270 UMS) at A2 , that would be sufficient to secure an A*, hope that helps

    Anyone else get (1,0) for the last question? Can't even remember at all how i even got to that, which doesn't look like a good sign D:

    y=9x-9, so gradient is 9 rings a bell?!
    I got either (1,0) or (0,1) (I can't remember) but other people haven't been getting that

    I liked this paper. It wasn't too bad. For the last question I got (-2,-27) however I got a gut feeling I wrote the solution in the wrong space. Did the last question where it asked for the tangent run from the last page inside the booklet onto the back? Because I didn't run onto the back for that question and I got a terrible feeling I wrote it in the wrong place

    I feel so stupid but was overly careful and put +/- 1/2! So stupid! Do you think I will lose a lot of marks? :mad:

    I thought it was that one where you had to find the difference between the points of intersection of y=4 on that curve?

    yeah i know, seems to be the majority getting (-2,-27) and the minority getting (1,0). would be a shock if it turns out to be right :P

    I think your method is incorrect... I don't think you've divided correctly.
    Do you mean the factorisation?

    Perhaps I made a mistake, although it still delivered an answer that seems reasonable.

    Mind explaining which part was wrong?

    If I recall, both equations could be divided by 1-x since the initial equation already gave you it in such a form and 9x - 9 = -9 (1-x)?

    Yeah, that was them.

    Just to say, for the first question you can just do:

     (4\sqrt{15})(\sqrt{3})



= 4\sqrt{45} = 4\sqrt{(9)(5)}



= (4x3)\sqrt{5}



= 12\sqrt{5}

    i think i got 6x + 2y -1 = 0 for question 8, anyone remember?
    I wouldn't have remembered unless you mentioned it, but yes that's exactly the answer I got.

    thought you had to find the distance (length) between the two points? oh well, i do have a bad memory...

    Yeah but if we are wrong, I am hoping we get some method marks, because I did some differentiating and subbing in

    k= -5
