Note that question 6) ii) , had 3 values, original value for x was -14.4 but you also get 14.4. You may want to check that.
No, sin was -ve and the values needed to be

yes, you are the reason that the answers to those parts are written on the paper.

that's not the answer you forgot to put it back into the P
What are you talking about? This is for the second derivative, to check that x was a minimum

COME ON GUYS SIGN THE PETITION TO ALLOW ARSEY TO RELLEASE EDEXCEL A LEVEL MATHS SOLUTIONS YEAR ON YEAR !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!
9. A pretty good paper thank God , except the binomial **** it went fine and made a calculater mistake when finding x in the last question. Arsey ain't doin anymore model papers too
10. can anyone remember the final calculation for solving x, question 9. I never simplified it to 17 but can't remember if my solution was the equivalent
11. For the sin one, I used a CAST diagram but then I drew a graph to help double check my answers. The answers that I got was right (i think looking at what most people got), but I was wondering whether my method (especially the graph to double check) will be accepted?
12. For the log question i got x = -2.19 but i had a brain fart and put that it also = 0, will i lose marks for this?

How many marks was it? It's hard to say, but I think you might as it is actually not a solution. Plus the question said give your 'answer' (not answers) to 2 dp. If you're lucky they may ignore the 0.
14. can anyone recall what P was equal to in terms of x at the start of question 9c?
