    A good paper I think, there were definitely some challenging bits so we can still hope for a low UMS. Lost two marks on 2b?!? Does anyone know how to do :

    tan(theta) = p
    Find Cos(theta) in terms of p?

    I think parts a and c were 2p/(1-p^2) and (1+p)/(p-1)

    Cos(θ)=1/secθ=1/(1+tan^2θ)^1/2=1/(1+p^2)^1/2

    Yep same!
    What did you get for finding values in the graphing question? I got something like 5/2 or something like that. Also, what did everyone get for the range of g? Mine had an e in it? So I said that 0 was less than or equal to g(x) less than or equal to (can't reember what i put, it had an 8 and an e in it)

    Decreasing, complete 50:50 guess as I thought the bottom was larger than the top

    Had an e in it, was like -4eto the 4 something < g(x) < something positive with e

    F***s sake edexcel do they think its a joke setting papers. Do they not realize that there are going to be student sitting these papers, and do they not realize that the results of these exams determine which uni we go to and ultimately our job prospects. Do they think this is a joke? I need grades and edxcel, you have f***ed my life. F*** you edexcel

    Increasing function. Gradient was
    -3k/(whatever)^2

    K is negative, so gradient at any given point is positive

    Therefore it is an increasing function

    That paper was pretty hard for C3. I couldn't get my head around the sec^2A + tan^2A question at all.

    Okay June 2013 was actually in fact easier. I am predicting even lower grade boundaries for this one, possibly 48 for a A. The June 2013 one had only one tricky question, here there were at least 3 funnily worded question. I mean which cruel person starts an exam in the manner in which they did?!

    I wrote increasing, since k was negative and I got dy/dx = -k/something squared

    So overall you get a positive value for all values for dy/dx, therefore gradient is always positive so f(x) is increasing

    I got increasing. Not sure though as I thought it was going from roughly 0 to roughly 1 as x got higher

    It was increasing, because the derivative was always positive (remember k was a negative constant)
    YEAHHHHH

    Only question I couldn't answer was the question 8 trig identity part A, how the hell do you do that?!
