    No finite limit as it tends to infinity
    Got the same. And for the 1mark question, it's an improper integral because the integrand is undefined when x=0 because of the denominator being zero?

    Used the quadratic formula to find the imaginary roots, then one is equal to a^2 -1 and one is equal to b^2 - 1
    Ok I did that but as my quadratic was wrong will I get no marks for that?

    You'll probably get 1 with error carried forward if the method is right.

    Yea, i just said integran undefined at x=0 should be enough for 1 mark

    I think I've dropped 10 marks.
    Do you guys think an A is achievable?

    Can anyone confirm the question about the transformation combination was asking about A and not A^4?

    65 will easily be an A on this paper. The A boundary has been around 55 for two years running, on arguably easier papers.

    The one with the enlargement and reflection or rotation. Think I did it on A^4, that's 5 marks down the drain

    It was based upon B not B^4

    two roots were (2+i) and (2-i) which are a conjugate pair. I just did the sum and product of theses to get z^2-4z+5=0, then if you times that by (z+4) you get the original cubic

    Im pretty sure it was B NOT B^4

    I got rotation 45° CW
    Enlargment SF 2

    I just did it by looking at tranfoatio B^2 and what it did to unit square. Then divided by 2

    Did people get an enlargement of SF 2 and a rotation about the origin 315 anticlockwise for the transformation question?

    Ahh right unlucky, I got enlargement SF 2 and rotation 45 clockwise?

    Oh ok. I did the sum and product of the roots, but then crossed it out. Crap.

    Yeah I got that, but an anticlockwise rotation of 315 which is the same thing.

    Yeah i didn't have a clue on this, but it was only 2 marks so thought it was the right thing to do and it managed to work out

    I got some huge number.
