The Big 2009 AEA Maths Thread! :)

I am so going to **** this exam up. The past papers are so ******* hard - harder than further maths imo and that was bad enough.

*waves* I decided against doing it I'm only doing Economics at university and it's not included in my offer, so no point given how incredibly hard it is. i'd scrape a merit at best...

Does anyone know if I have to write it on UCAS if I fail?

Yes, even a U has to be declared.

Oh okay, thanks. I don't think I'm going to do it then!

You can drop out now and you dont have to declare it on your UCAS (and you dont get a grade for it i think) as some lower sixth students were allowed to cancel it.
But if you sit it and get a U it has to be declared yes.


Also, have people actually been revising this?? O.o Didn't think it really needed revising its just aea.. I suppose if it's part of a uni offer you have an excuse though

and lastly, whats the grade boundaries? ive heard loads of numbers thrown around liek 50% merit 80% distinction? are they in the ballpark?

Thanks only 50/70 then, thats out of 100 i take it?

Yep, and it doesn't seem to vary too much... so 75 should guarantee a distinction and 55 should guarantee a merit (of course this is difficult to estimate due to the S & T marks...)

if the paper is going to be as ''hard'' as june 08 then i think i could get a distinction... -.-'

the first thing to note for part (b) is that the line they gave you is perpendicular to the line in part (a) ...! they also gave you something really useful(q>12) that means now you know where the line lies... try to do a little sketch i bet you will figure it out...!

for a
(ii) you can do it the hard way and prove that (using identities) that the denominator will equal zero ... or you just refere the expression to your diagram... arctan(1/2) ===> angle between the x axes and the line joining the origin to the centre of the circle
