    Grade boundaries will be high I reckon, was a 'easier' paper, I think I dropped about 4 marks(at a push) and the majority of that was the the show that, I can't remember much but stuff like k=7/2 and B was nine hundred and something b=1/9a-5/9 the other logs question X= -2.19 and 0/no solutions, sinx= 1/4 or 2(no solutions) and solve and minimum perimeter is like 120m or something once you solve dP/dX and X= 16.6 something, radius of circle is sqrt 34 and I can't recall much more
    I got B = 936 I, b=(a-5)/9, sinx = - 1/4, and the rest the same as you.

    do you think we will lose the marks for e) and proving it was a min point?
    I don't think we will lose any marks because one mark is for differentiating correctly and subbing in our value of x and the other mark is for saying its >0 so it's a minimum.

    The value of X was meant to be subbed back into the formula for P giving you 120m not 16
    Yeah that's what I did :P I only did a, d & e on question 9 - The show questions were too difficult for me. How did you find them?

    I got that too.. I also thought it was unusual numbers :/
    I thought that too, but considering your set of coordinates was quite large, 10 and 13?? It seems about right

    They were alright, although the number of marks allocated were misleading, considering I think it took me an entire page for b and c

    x was 16.6339... which = 17, then you had to sub it into P to get P = 120
    I got the same but I left my answers to 1 decimal place...(x=16.6 and p=120.something) did the question ask to leave the answers as integers? would I still get full marks for that question?

    question nine was a middle finger from edexcel
    lool that question was a madting, never seen something like it. all of the other questions were fine apart from the 2nd part of the log equation.

    Pretty sure B was one thousand and something

    It said to leave it to the nearest metre, so it'll probable lose you 1 accuracy mark

    B was definitely 900 and something

    the correct value of k was 7/2

    I got 120m for the perimeter also, and a small decimal is >0 therefore a minimum.

    As long as you stated that its greater than 0 so its minimum
