OCR C2 - 15th January watch

1. O__O
I thought the paper was alright, even though I know I lost a fair amount of marks on it because I ran out of time...-__-;

What did you guys think of the paper?
2. I failed at the last question :/ I did the first part of it right though o.o

a= 3
b= -4

P= 3
q= 5

ughh ican't remember anymore :/
3. Ditto.

perimeter = 10+6+13+4.4
I cant remember the area.

I PROVED THE LOG!
4. I failed the log T_T DIE LOGS DIE I HATE YOU.
5. What was the area between the 2 curves? :O
6. OMG! i failed at the logs one!!!!!!!!
arggghh!

Bionomail expansion --- what did you guys get?
7. Does anybody know the answer to the arithmetic question where it said the two sums taken away =1256 (i think) and then you had to find out what N was?
8. For the area between the curves I found it to be 5.33333 o.o
For the binomial expansion I had some weird answer. I was struggling with the signs O_O
And wtf is the coefficient of w^6???

I found N to be over 100... I cant remember exactly.... I hope I did it right though! ><;
9. I totally failed that paper because of stupid mistakes I think I'll get a C in it :/

i didn't get the same area between the curves

When finding N was it a quadratic equation?
11. yeh wth was the coefficient of w^6 ??
erm other hard questions was the log one and summation on geometric argh
but still i did well

13. it was so hard! i dont think i answered a question fully!!
14. I got the N answer using a quadratic equation. I got 27 but I'm fairly sure thats wrong hope for some method marks!

did you use the geometric or arithmetic formula?
16. Arithmetic. Is that wrong?
17. i got N=16
area between curves= 16/3
coefficient of w^6= 35/256 or something around that but i think that might be wrong
i got N=16
area between curves= 16/3
coefficient of w^6= 35/256 or something around that but i think that might be wrong
YAY same area.
for coefficient i got -17.5
19. N was a quadratic with no constant at the end o.o
it was something like
7N^2 + 15N = 2512
N(7+15N) = 2512
N= 2512
N= 167 o_o

That sequence was an arithmetic progression...right? please tell me yes.

I dunno, I used this as well.
