    Here's the mark scheme, when you get the value of theta using the reflection matrix you get a completely different value for theta.
    I did this paper yesterday and got theta as 75° - 150°/2 (with an enlargement of 2rt3)😕

    You need to use CAST method to get the right value for 2 theta otherwise the calculator only gives you principle values

    For that reflection Q:
    Other correct alternatives’ include eg Enlargement sf: − 12, reflection in y= tan15x

    They accept a lot of alternatives, you don't need to use the CAST method.

    I actually think that was too horrible - where were the numerical methods, though...?

    It wasn't a hard paper, I knew how to do everything, just ****ed it all up. None of my numbers worked, and that meant I couldn't finish question 9, because my answer to part a just would not work out.

    Shall we say that all of my university aspirations have just been flushed down the drain?

    Your talking about the matrix one where your answer would be right, I'm talking about the general solution part b

    Was the 'q' question
    w^2 +(4+i+q i)w +20 = 0

    with w = p+2iq and w^* = p-2iq?

    Yes
    Thanks - this was the only one where I think I made a mistake. I got q as -7, -1 and 5. I didn't like 3 values and my Casio didn't agree with me I think I have one sign error so a probable 1/5 marks?
