I tried qn 10, I got up until the limits i got 1/2(e^(-x)sinx - e^(-x)cosx) and then put in the limits and ran out of time before I could complete..but I feel like I would've gotten it with abit more time! the xy=6 and x^2-y^2=5 was number 12! the complex number question where u had to find the roots of that number and its conjugate!

I've seen it at 74 on some papers. And today's Paper 2 was harder than those paper's for sure.
But this paper one was certainly on the easier side, so I'm guessing 95.
Ah fair enough - I wouldn't think too much about it though. I came out of my papers last year thinking Paper 1 was straightforward and Paper 2 had the most messed up section B I had ever seen. Paper 1's grade boundary came out at 79 and Paper 2's was 84 or something along those lines if I remember right. Each to their own I guess....
I got the roots for the 5+2i, revised that the night before . I'd give it an 8 in relative terms, usually I find P1 easier than P2 for this year it was the opposite. I don't remember them exactly they were 2, -2 and 3i I think.

Ok, I took my time to write this out for you guys
Oh I got that question pretty much then except i didn't put pi - and pi +! I put 2e^(i(arctan(root(7)/3)) and 2e^i(arctan(-root(7)/3))! Which is I suppose the same thing because pi plus gives u a positive sign and pi minus gives u a negative sign!
People in my class didn't like paper 1..so its not everyone of us who thought it was okay! May 2009 TZ2 Paper 1 is one of the easiest papers I have ever seen and the boundary for that is 91! Even though our paper 1 was pretty good, I'd still say May 09 TZ2 P1 was way easier!
