Well now we can discuss it :wink:

I didn't sit it, but how would you compare it to previous years? My early impressions are that it is difficult by comparison to past papers.

Yeah I thought it was tricky. I had a hack at number 1, showed that QR=PS (pretty easy) and then tried to show that QER+PES=180 so that we could make a cyclic quad out of the two triangles QER and PES but alas, I couldnt do it and spent way longer than I should have. I also had a go at number 4, but again didnt quite get it, I made some bad logical errors. I decided K=3 was sufficient and then put forward a strong inductive argument using

an+bn+cn=(an−1+bn−1+cn−1)(a+b+c)−(ab+bc+ca)(an−2+bn−2+cn−2)+abc(an−3+bn−3+cn−3)a^n+b^n+c^n=(a^{n-1}+b^{n-1}+c^{n-1})(a+b+c)-(ab+bc+ca)(a^{n-2}+b^{n-2}+c^{n-2})+abc(a^{n-3}+b^{n-3}+c^{n-3})

Oh and I also worked out that 3 is equivlent to showing that given a large enough 45-45-90 triangle lattice that has a two colouring then there we can find three points in the lattice of the same colour that form a 45-45-90 triagngle.

Q2 looks the most accessible to me...will have a crack later. Strong induction (or possibly an obscure contradition argument?) is probably the way to go on 4, 3 looks like contradiction. 1 is geometry so I'm definitely not going to try it...maybe areal co-ords? :tongue:

Got my last offer (from Bristol) last night. Now to decide on firm and insurance........

Try Q3.
do you have a copy of the BM02?
Here.

Thanks :smile: quick glance and 2 you could probably do with a lot of thought and possibly an induction/contradiction. 4 looks like it can be done, but the algebra manipulation will probably cause me to make a mistake :tongue:

Quite a few people, but I'm pretty sure the majority do physics (just cause mathmos tend to like physics I guess haha).

Which unis have you applied for?

Well done mate. Well I guess that's insurance settled for you? :tongue:

Yep, I haven't done physics and I have 5 offers, it really doesn't matter

That's weird. How come? Any theories as to why? :tongue: Or do they often do that?

Someone on here has an offer for Maths + Econ (and I've seen another for Actuarial Science).
