these were my answers, can someone give me any indication on how well i done.

1a. x+3/x b, not sure
2a 2<f<11
b 5
3 a -144 p 3/4
4 Graphs which were easy
5b interception only once
c chenge in sign when sub numbers in
d 3.921
6 a proof
b p=1 c=4
c k=9 q=8 pi(9+8ln2)
7a x+2y=14
b x=14
c p=97 q=10/13 97+(10/13)ln2
8i proof, alternative forms of cos etc
ii a proof
b i was not sure --- 0
c 135, 315

Please can you post the answers or give me an indication on how well, i.e a predicted score, considering I got the graphs all right.

Here are my answers... please fill in the gaps since i forgot some questions...

1a. x+3/x

b x = 1/5

2a 2<f<11

b lamder (however u spell it) = 5

3 a -144 p 3/4

4 The graphs... thoguth it was pretty hard... can't really draw it out in this forum...

5a draw the graphs

Y = x ^ 0.5
y = 2 - e^-X (this question is a bit tricky.... )

b they cross once... let both equations above equal...

c change in sign after subbing numbers

d forgot....

6 a A = 1 B= 2 C= i forgot...

(1)x + (2)y = i forgot what...

b forgot

c pi(9 + 3ln2)

was that 6 or 7?!?! forgot...
yeah correct me guys...

Crap, why oh why didn't I resit P2 this year? It's so much easier this June!

I did the Jan 03 paper which everyone found harder than usual, much like the Jun 02 P1 paper and especially the horrifying P3 of Jun 03 being much harder than their predecessors. Oh well, I guess I missed out on some extra marks overall. I only got a 90 on my P2; people sitting this paper could easily get over 95 and possibly 100. Argh. This sucks. The people who got 60-ish on the Jan paper found this paper shockingly easy, and some from this category, mentioned that they might get close to full marks.

Why can't Edexcel set papers that are consistent in difficulty?! Very pissing.

1. 1/5

2. 5

3. p = .75 and A = -144

4. 1st graph shift to left
2nd graph take everything under x axis up
3rd graph reflect evrything rite of y axis onto left

5. iteration was 3.921

6. V = pi(9 + 8ln2)

7. R = 97 - 3ln2

8. the other two answers were 26.6 and 206.6

Anybody hav the exact same answers??

did you put 2 <= f <= 11 ?

im sure just putting < would lose marks.
