I can easily predict the paper, like usual, will be a massive pile of masturbation. Absolute horse ****e.
Good luck anyway, but I get where you're coming from its usually too hard!

I think they might do a linear laws question... and i bet its going to be harder than last years... which was seriously challenging!

Pretty sure it's the expanded alpha^2+beta^2 all squared

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.

Edit: what happened to my indentation?

for 4b I got 1 as you have to state the value of n, atleast that's what i thought

n=2 anyway, but you are meant to give the value of the solution closest to 200. This is the value of x. If you have written the value of x down you will probably still get the marks.

Shouldn't 3a) be 2+11i

I think it was (2+i)^3?

= 2^3 + 3(2^2)(i) +3(2)(i)^2 + i^3

=8+12i -6 -i

=2+11i

yeah, it should be 2+11i

Hi for Q 6, I got k as -3 since k is less than <0 and then I substitute x to x+3. How did you get 4 ?!

It's K=40 on 7)c)ii). As solving the cubic = 0 gave an answer of ~39.579...
So when K=39 the value of the sum to 60 was less than the 1060.. value.
I'm not 100% though

Yo . Remember at the counter . It's k+1. Although I got 39. I think k is 38

Hey ! X should be x+3 . Since the change is towards the variable x . So replace x by x +3 that's what I think . Hope some one can correct me if I am wrong

My 1c was what you got but squared
3a was 2+11i
How did you do 3)b)ii)?
for 5b)iii) I got 256sqrt(2), did I need to square 256?

How did you even get K?

Could you do an unofficial mark scheme thread because most of these look good

I got the same as what that guy got . I can't remember how I did it , if you remember the question I will help you . And the question about k , if you can give me the informations from the previous parts then I can help you
