are you sure it wasn't -3-2i?
Probs man.
2. i seem to remember plotting Z1 in the bottom right of the argand diagram you see.

It was definitely 3-2j
4. I gotta admit the argand diagram got me a little worried, did anyone else get surds on some numbers?
5. 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?
6. 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?

i plotted Z1-Z2!!!

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.
http://www.mei.org.uk/files/papers/fp106ja_pcx12a.pdf in question 9vii it is very similar to the one today and says 'Transformation many to one'

well seeing as everyone else in my class did it that way then yeah its probably right (dammit for me)
11. 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

Can you take a photo and upload it by any chance ?
14. that paper threw me a little, didnt expect a induction q in section B but i thought it was alright.

Yeah exactly that, its only 1 mark but pissed off cus of it rofl.

Could i get in trouble for doing so? My head of maths would murder me if he knew i took it out
17. (Original post by abdcefghi)
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
