hi-five!

Erm, I'm currently doing, M1,S1 retake. C4 and S2. I've done, C1-3, D1. confusing lol. Are you doing AS?
Oh ok.
Yep, I've done C1, C1, M1 and now FP1. I'll be doing C3, C4, M2, S1, D1 in the summer to get A level maths and AS FM.
3. Erm the proof by induction questions, I wrote

Therefore n= k+1 from the assumption that n=k is true, also true for n=1. Therefore by induction the statement is true for all positive integers, n.

At the end. Is that correct? What's some people saying about U2...

I think they met at (5c, c/5) or something like that. You had to find t which was -5 or 3 and then put it into initial x and y...

Can somebody post the paper as I remember most of my answers and want to see how I did
Woo yeah that's what I got

O wow. So what did you do last year? I would recommend anyone to do FP1 during A2.

I meant C1 and C2, oops. Yeah, I did AS Maths last year. Finishing that off for A2 this year, and then doing AS FM as well.

For induction I always write
"If it is true for n = k then it is shown to be true for n = k + 1. as it is true for n = 1, then it is also true for all n e Z+ n>1"

Cool.

Think it's similar to what I wrote. I needed more paper for the second induction question as I wrote question wrong for the first part.

I think it was ok. But looking at the poll, the grade bounds are going to be HIGH!
8. how did people solve the matrix questions where u had to find p and q...did you do simultaneous equations or find the inverse matrix...i went with the equations myself...seemed to make sense to use it...anyone?
9. For the summation of series question, did people get like 92080 or something similar to that? I can't remember the exact number though...
and for the last matrix question, did people get C as (4(sq)2 , 3(sq)2) or something along those lines?

cheers

I just remember the numbers 1 or -1 and 7.
11. ^i think i got p=7?
cant remember

well x= 15c and -c = y, and you just plug these values into the equation. You can then cancel out the cs, and you get a qudratic with the ts. I solved, and got two values for t.

And it said that a general point P on the curve is: P(ct , c/t)

So you just plug the value of t into this and you get two points. Thats what I done and I got it to be:

A: (3c , c/3)
B: (-5c , -c/5)
I got that too!!

what was n? it was 15 and something else...

0.5n(n+2)(n^2+7)
14. (Original post by Khodu)

0.5n(n+2)(n^2+7)
15 and the other value was 10 i think, but you obviously had to use 9 because 10 was included.

No I remember using 14. There was a larger number... Was it 25?
16. Alot of people found it easy, so the boundaries might be high.

Does anyone know if they can raise, say, the 'A' Grade boundary, above 80% btw
17. (Original post by Khodu)

0.5n(n+2)(n^2+7)
it was 25 and 14 wasn't it...cuz it was r=15 to 25...so u use 25 and 14...and im pretty sure it was....0.25(n)(n+2)(n^2 + 7)
18. (Original post by Khodu)

Yeah it was definitely 14! I remember now.
So what did you get?

Yeh, I think if ire emmber correctly, 95282, or something like that.

ALso, for that matrix one, I remember that the answer was the same as the B matrix, but the other way round and one was a -ve. So yeh

(-4(sq)2 , 3(sq)2)

I can't remember properly though

Did people get root 50 for the length OA?

i remember using 14 and 25 too
