    I gotta admit the argand diagram got me a little worried, did anyone else get surds on some numbers?

    yeah 3-2i hahah, of course its 3-2i if its bottom right. i dont think alot of the time when i type or write, probably why i'm heading for a poor result in that exam..

    in general how did people find it?

    it was much easier than jan2013. I really wanna know though, for the z1+z2 and z2-z1, did you guys add and subtract first and then plot a single point, or do the thing in the textbook where you draw a parallelogram and for the subtraction draw the arrow ? I did the second one, reckon I'll get the marks?

    I added and subtracted, which gave me some numbers involving surds. Is tis the correct way? I dont know the vector way of doing it

    You mean it was Z2-Z1? :eek:

    i plotted Z1-Z2!!! :unimpressed:

    If you've done that method correctly, you'll still get the marks.

    I wrote that it does not have an inverse, as the determinant is 0.

    As for the paper - it wasn't too difficult but I know I have made a few silly mistakes.

    I can confirm, z1 = 3 -2j looking at the paper now.

    if you plot z2-z1 it will be arrow from z1-z2, make sense? I think you've done it right? fingers crossed

    Wasn't it starting with Σr^2 -Σr -n

    Then factorize out 1/3 then take out n and if you multiply the stuff left in the right hand side bracket you get n^2-4 which is the difference of 2 squares so its (n-2)(n+2)
    Well then... Probably lost a couple of marks on that
