1. were u supposed to integrate between 27 and 0 for the last question and then take away the area of the triangle?

i have a bad fealing it was i did summin silly like 27 and 9 for the boundaries and then took away the area of the triangle

will i get any marks?

Yes, probably most of them - provided your integration was correct.

what did u get as ur answer?

I didn't sit the exam - sorry (2nd year university). But it's generally the method for these integration questions that count. Maybe you were right (I don't know what the question was).

Weren't you supposed to integrate between 0 and 3?

the y value was 18

for the question i got area under graph as 36, and the triangle area as 27, giving the answer as 9cm2.

May be completely wrong

the value of y was 27 i think..pretty sure...then again i mite be wrong
7. it was between 3 and 0 wher you needed to integrate, im so stupid i integrated between 3 and 1 losing marks

Can you remember the questions? dnt think it went the best

That's what I did and it looked correct to me. Minimum point on the curve was 3 (x co-ordinate) so you would integrate between 3 and 0. The curve was y = x^2 - 6x + 18 so the y intercept would be 18. I think I got 9 as the area of R.
9. I also got 9 for the area of R
10. i take it this is the edexcel paper?

Yes, its Edexcel.
12. ok......just i couldnt remember getting that question but thats cos i did the OCR one heh
13. Yeh I intergrated between 0 and 3 then took away area of triangle.
How did you guys find it? I thought it was alright, but I was hoping for a solid A. Methinks i prob managed about 55 to 60/75, probably a mid B? that area of a sector of a circle was annoying as well, when i finally figured out how to do it, the time was up .

Ah well, I'll just retake it in June (i think its the same day as P3)
14. i got the area under the graph to be 9.

how did you verify that the line was parallel to the x axis? i got the same x - values of 3 but didnt know how to explain.
15. ok this may have just been me. But did anyone else notice the paper was longer than all the previous P1 papers. Im sure ive never done a 9 Q paper. N i seem to remember somin like y = 18, then when intergrate got 36 then minus 27 for triangle.
16. 1. Yep edexcel
2. and yes i got the area of R to be 9, however not cm2, just 9 , or 9 units to be precise.
3. i do afree with u syncman, it was a longer paper than all the others. when i saw the table on the front page going up to question 9, i was schocked, coz it's ually only 7 or 8 Qs, but it was a good test.
4. for the proving it's a parallel, well since u've got two x-values being the same which is 3, meaning u'd have to divide by the 0, which is not possible thus it's parallel, thts wht i wrote, although i might be wrong
17. yeah because there is no change in x they it must be parallel. thats wot i put

9 units squared, to be precise-er!

crap, I put cm squared.

Oh well
20. What did everyone think of the paper compared to other P1 papers? I thought it was easy but a bit longer than the others.
