On the last question on paper one, would 5r13 be the same as r65. If it's not does anyone know how many marks I'd lose for 23. (c) if I put both my answers in the r65 form? Cheers!
Also, for paper 2 if I didn't find the limits but worked out what to integrate (i.e done top-bottom) would this warrant a mark?
wahoo, got all the same answers as ukdragon, not sure about the multiple choice-anyone posted correct answers yet?? anyway, should be enough for an A, maybe band1?
For Paper 2, question 5a) (i) I know that the answer is (6 - x^2), and this is what i wrote.
However i only wrote this as i knew the area was 12x-2x^3, and for the area of the rectangle it is 2x (base) times height. So i took out a common factor of 2x, giving (6-x^2)
Then for (ii) i just wrote (2x)(6-x^2) = 12x - 2x^3 as required.
Would i get any marks for this?
so did anyone get for 21.a) 15y=-6x+216
then put in the points of T, to get 180=180
c) but for c it gave ratio 1:2 which i know is wrong. how many marks roughly would i get....if any....
Has anyone's teacher said whether 2010 paper was easier or harder than 2009?
I am wondering so I can guestimate the grade boundary
My answers to the MC:
1)A 2)C 3)D 4)A 5)B 6)D 7)C 8)B 9)C 10)B 11)D 12)A 13)B 14)C 15)C 16)A 17)B 18)B 19)C 20)A
our teacher thought paper 1 multi choice was same as last year, part 2 was slightly easier.
thought paper 2 was WAY more difficult that last year because the questions were less "accessible" (i know thats not how u spell it) meaning they were harder to actually start and the logs one was hard.
is 16. really C??? YUSSSS! please be C
