Horrible paper I missed a few questions because I ran out of time. And the first question just put me off. I made the last question up...and I didn't use the quadratic formula so I must have thought it factorised. -_-
Pretty sure I got the A* the paper was quite hard but I guess my revision came to use
Some of the ans I got were
C was 256 - 2pi sq. Hence it was 6m to the nearest metre One was (-50,0) There was a 32 in the cartesian equation Sinx = 196 and 344 Vector was 5 1 2 I write some others later
I'm not sure, I needed 87 on this paper to get an A* overall, and I need a D on my M2 paper to get the A* provided that this averages an A*. I'm pretty sure I'll get an A overall but idk if it'll be any higher than that.
To get A*, you need to get 90UMS in C3 and C4. All other papers are irrelevant. Even if you get 100UMS in every other paper, you still MUST get 90UMS in C3 and C4 for the A*.
Wait I may not have missed out that 3 marker. Was finding the coordinates the question before finding the cartesian equation? And x and y were in parametric form? I need to see the paper to remember if I did it.

Isn't it that you need to average 90 UMS in C3 and C4, So for example,

if you're the person who was getting emosh over dropping 15 marks, don't worry! Boundaries were 53 for an A in january 2013. I genuinely think It'll be lower than that.
Well I think I did OK but I incorrectly evaluated the function in 8b and got x=2.28. Some answers: Trig polynomial: sin(θ)=43−(17) θ=196∘,344∘ Question 7: dtdh=1.3cos(6πt) Question 8: a π4tsin(41πt)+π216cos(41πt)(+C) b 16x2=π4tsin(41πt)+π216cos(41πt)−π216+256 x=3.65(=3.64621…) (x=4.2 comes from using degrees other answers, I have no idea) I may do a few more later.
I can just about remember my final answer - x = 365cm. Note that doing your calculations in degrees rather than radians would result in an answer greater than 4m - I know, because I made that mistake and frantically corrected it with three nanoseconds to go.
Definitely the hardest paper I've ever seen, it was as hard as FP3! I resat this for a A*, looks like i got the vector questions slightly wrong, and missed out question 7! Not impressed
