AQA A2 MFP3 Further Pure 3 – 18th May 2016 [Exam Discussion Thread]

Alright, cool. I was worried it would end up being a suprise question 7 that everyone ends up flopping. Right in between the 14 mark polar co-ordinate question 6 and the 16 mark polar co-ordinate question 8.

There are several ways (I think like 4) to do this question but i think using sine rule is the easiest
where K is (pi - pi/6 - alpha)

Btw in those DE Qs where it says as dy/dx -> 0, x -> infinity... is it ok to say:

e.g. dy/dx = Ae^x
0 = A(infinity symbol)
therefore A = 0

???

I would disapprove of that (strongly) but I'm not sure what the examiners would do.
In general don't use infinity as a number in equations; it's not mathematically correct.

Better just to say $e^x \rightarrow \infty$ as $x \rightarrow \infty$ ;
hence we must have $A=0$ for $Ae^x \rightarrow 0$.

Good luck everybody! And goodnight to whoever's off.

For whoever is hanging around, what would you say the hardest questions in the entire FP3 library are? Got time to do some questions now but don't want to spend time on a whole past paper so looking for some challenging ones.

Can anybody help with question 8 bii june 2014?

Don't quite understand the mark scheme

All I could find were polar questions tbh. Although I have only just realised that I didn't do the June 2009 paper which looked really nice and now I'm sad .

Btw is anyone going to bristol uni ( if u pass fp3 obvs)

Yes! It's my firm. What about you?

Thanks! Any polar questions in particular? I've done all the recent papers but I don't see why I shouldn't go over the tough questions again anyway
