# AQA Further Maths FP1 June 5th 2015 watch

1. My answers' other than show that questions:

1) a) a+b = -3, ab = 7/2
b) 4x^2 + 45 = 0
c) a^2 = 1 + 3/2 sqrt(5) i, b^2 = 1 - 3/2 sqrt(5) i
2) a) Undefined at one limit of integration
b) Does not have a finite value
3) a) 2-11i
b) i) q=20 (z^3-11z+20=0)
ii) z^2- 4z + 5
iii) z = -4
4) a) x = {-5 + 120n, 35 + 120n}
b) 235
5) a) c=4, d=-1
b) i) -16I
ii) enlargement scale factor 2, rotation 45 degrees clockwise
iii) Fromleft to right, top to bottom: [[65536sqrt(2), 65536sqrt(2)], [-65536sqrt(2), 65536sqrt(2)]]
6) a) Hyperbola crossing (3,0) and (-3,0)
b) y = 4/3 x + 4, y = -4/3 x -4
7) a) 39.60
b) n(n+1)(2n+3)
c) i) 2/3 r
ii) k = 39
8) a) y = 1
b) (1, -1/2) and (-3, 3/2)

Not sure if they're right, feel free to make corrections.

Indentation got messed up

that one matrix, it was really easy but i think i might have got the image and point the wrong way around and lost those marks
You haven't got it the wrong way around, yours is right.
3. (Original post by a123a)
Yep. What mark do you think you have got?
I'm too afraid to count
Well I went full retard on Newton Raphson, I don't know how many marks that was
Made algebra error with sum to 60 thing, got k=39 but then the cubic didn't match the beginning of the question, so I don't know how many marks I'd get. Hoping for ecf
Went full retard for asymptote, got the original asymptote but forgot the bracket for +3. One mark off I think
The B^17 l totally got it wrong 2 marks off

I may have lost method marks for few questions, I hope they are lenient
4. what did people get for the newton rhapson one?
i got like 39.59
also when you had to prove that summation, was it n(n+1)(2n+2) or 2n+3?

2n+3, I also got 39.59
6. Anyone got their average of grade boundaries, and 100 UMS raw mark? I'm hoping around 68-69 will be enough for 100 UMS

The 60 sum one was 4 marks.
Also could you remember what you got for Q? For the complex question. P=-11 and Q=20?
8. The ws no question on differentiation either :/
9. anyone have a scan of the paper?
10. (Original post by -jordan-)
2n+3, I also got 39.59
i think i got the summation one wrong

what do you think the grade boundaries for an A will be? higher than 55?

Indentation got messed up
I got all those apart from 7cii but I know where I went wrong in that one
12. I had all the same answers as you apart from B^17 and 7a, I'm pretty sure it had to be an integer?
should be (x-3) in brackets as the hyperbola was translated 3 to the right
It was 3 to the left as k<0

55 seems reasonable.
15. the second bracket in the summation was definitely 2n+3, right?

oh ffs

Yes

7a was a Newton raphson question so it doesn't need to be an integer.

Indentation got messed up
Wasn't it 2+11i?

7a was a Newton raphson question so it doesn't need to be an integer.
There were two parts. The sign change and the newton bit.
