Can somebody explain 4(c) from 2003.
I don't get whats going on at all there, tangents coming from binomial expansions??
If you let , the binomial expansion will make it very easy to find , as all but one terms will disappear. Similarly, if you differentiate the expansion, will also be very easy to find, by substituting into your expansion of . You can then use the standard straight line formula to the find the equation of the tangent.

EDIT: Although this is likely to be the method they are trying to guide you towards, there's no reason you can't go back to part (a) or even the original equation to find and , although IIRC there are several marks available in the paper for neat answers, which you might lose by going for the latter approach.

Just did the 2007 paper and for me it was by far the nicest paper (excluding specimens). In what way do people find that the papers vary in difficulty? For me, excluding specimens the papers have gotten easier over the years except for 2004 which was a pain. (Ofcourse this may (hopefully) have something to do with the order in which im doing them, I might be getting better )

hmmm i found 2005 was the easiest... and 2006 was the hardest for me .... i really dont know what to do-.-' i did the special paper and these aea past papers ...
5. Re: The AEA/Oxford/S Paper superthread
Just attempted my second paper, which really wasn't much better than the 1st one at all lol!
I actually thought i was good at maths before i started doing these papers today lol!

I have at least one more useful resource to share for preparation, I might extend my S-paper thread later, although I found that these are slightly easier than the older S-paper questions. I've done the none STEP ones + a few STEP Qs that looked easier, but I can't be bothered to type up all my solutions atm maybe after the exam

Here's a key for the questions come from:

QCA/Edexcel: AEA questions so you've probably seen them before
OCR (9470)/(9465): STEP II/I
AQA (AEB): I'd do these and the ones labelled Special papers (these are more recent like 2000)

The AQA and S-Paper ones follow a VERY similar style to the current AEA in my opinion so I found them quite useful

Hope this helps

Do you guys think the examiners would get pissed off and be more disinclined to give me marks if i did questions in a random order?

Im having major difficulty with these papers so I would be happier banging out the 3 questions that I know i can do well first to build confidence ato try and attempt the rest.

Aghh, i breezed through A2 Maths/Fmaths but im doing terribly on these buggers, i really hope its just due to lack of focus as alevels have finished!

Edit:
2006,3(b), could somebody explain how to do this please! cheers

You can do questions in any order Just make sure you write the order you did them on the first page. They won't mind.

So from the previous part we can rewrite it as this:

From here either or

We can rule out because that would give us y=x which is not true for the given range ( x>y>0)

Thanks, i did manage it in the end yesterday but forgot to double edit the post!
14. Re: The AEA/Oxford/S Paper superthread
Anyone know where I could get old special papers/ anything else of that kind of level? I've got all STEP papers and AEA papers which should keep me busy for quite a while, but I'd like to have a look at the old special papers too.

I'm not sure if they have been released yet. I know the AQA papers arent released till after the following sitting.

Hmm. Anyone know when the closing date for AEA entries is/was? I'm not sure if I'm going to take it or not, and after looking on the Edexcel website, I couldn't seem to find a date specifying the closing date for entries
Hey I don't agree with your answer to Q13 on the S paper thread, have a look.

The "official" ones aren't out yet but I'm sure they'll be somewhere on the forum if you do a search.
