    Ask here and I'll mark it for you.
    I'll have a go at this tomorrow, thanks for the resource. Should I send it over when I am done?

    I don't suppose anyone has done any worked solutions to these questions? Thanks!

    I have completed the paper, it was quite challenging and one question stumped me as I have never come across this concept in either FP1, C1 or C2. Did you want me to send you the pictures of my working.

    Which one stumped you? If it was the complex loci one, it's more of an FP2 question.

    Did you two get question 2 on these? That one totally got me!

    Yes that's the one that got me. I'll have to look up how to do it.

    Yes I got that one, do you know how to do it now ?

    I haven't done anything except give them a cursory glance, I've been done with this module ages ago.

    At a glance, it doesn't seem like they've written Q2 properly unless they expect non-exact answers. I could (probably) be wrong, though and can't really be bothered checking.

    Don't bother - it's FP2.

    Sure, I did a different example so that you can try and attempt the question in the paper again.

    The thing is that with this example, you get ugly crap like a = \pm \sqrt{\frac{1}{2} + \frac{1}{\sqrt{2}}} which is just unsightly.

    Not in your example; in the question paper. What did you get for \sqrt{1+i}?

    Oh okay, good.

    I got 1.099 + 0.455i

    I would have expected it in exact form, no?

    this paper is insanely hard

    1.) I can't quite get this one
    2.) sqrt(3-6i)
    3.) 4n-4n^2
    4.) not a clue, I've never seen anything like this before, some help would be appreciated.
    5.)x=1,x=(3-i),x=(3+i),x=(-1-2i),x=(-1+2i) [is it realistic we will get a quintic in the exam?]

    need a break after solving that quintic, let me know how I've done if you have some time

    Q4 is an FP2 topic, not an FP1 one.

    Oh I'm so glad, I was thinking this was maybe written before the specification change? By the way I had a look at the January 2016 IAL F1 paper, there is a question there I just don't understand. Is F1 different to FP1 or is it significantly harder but the same content?.
