    Am I the only one who put the x coordinate for Q in terms of cos? I got  cos(\frac{3}{2}) as my value of p was  \frac{3}{4}
    i did that because the question asked for x coordinate.

    How many marks do you think I would lose in question 2 as a whole if I got R at root 29 but alpha as -1.91?

    For the vector of C did anyone get T=4 and then sub it into L. I can't remember the exact vector but definitely got T=4.

    As for the acute angle yeah I got 20something but it looks like most got 60 so whoops.

    If anyone does a mark scheme can someone PM me a link? I'm just so disappointed in myself.

    Me too !! Did you get a horrid differential equation for x in terms of t? And did you get r=3 for last question? How did you show h(x) is decreasing? I just subbed in x vales>2 amd found it was decreasing. Differentiation doesnt work as its increasing in thar case.

    Exactly what I did
    I just said because the bottom is squared its always +
    Top is negative
    Domain of x is ....
    Hence h'(x) < 0 so decreasing function

    Did anyone get 11,0,0 as one of their co-ords for E
    Yes! At least, I had one that was (?, 0 ,0) so I assume it was the same. Thought I'd completely messed that one up cos my friend got weird fractions

    You're such a ****, stop scaring that poor person! I wrote part of my answer to question 8 on the very back sheet so there definitely wasn't a question 9.
