# Edexcel FP2 Official 2016 Exam Thread - 8th June 2016 watch

1. (Original post by Geraer100)
With modulus(w)<radius you mean the radius of the circle in the w plane?
Yes.
2. (Original post by david0906)
Do tricky polar coordinate sketches (eg r^2=a^2 cos(2theta)) ever come up? - I've not seen any in past papers, and haven't learnt them... yet
I know what you mean, I've never seen them come up and they are the hardest thing as there is NO practice in them!

I'm a little bit worried since my grades are fluctuating a lot (from Cs to A*s), purely because of silly mistakes :/
Same here, some day get an A, another a C. Really stupid.

yeah I feel you, same here. really hoping for a straightforward paper tomorrow.

I'm hoping it'll be like June 2014-15, with no hard polar curve questions since they contained quite a lot of good straight forward questions.

Hoping I got the 100UMS in the M3 so I can afford to get 79UMS in the FP2 for A* lol..
5. Where is the mod(z)=3 coming from?

The book is your best friend then...

Typo on solutionbank
8. Ahh, thank you!

Try pre09 papers
10. Can we use a pencil and a compass when you have to sketch curves/circles?
11. (Original post by wr123)
Can anyone show a way to get from the top to the bottom? I honestly can't understand the (d^2y/dx^2)(dt/dx) part..

Attachment 545397
Differentiate dy/dx wrt(x) using product rule on the bit in the bracket => d2y/dx2 = -x^-2(dy/dt) + x^-1 (d2y/dt2) dt/dx.

Then, given dy/dx = 1/x (dy/dt), 1/x must equal dt/dx, so replace dt/dx with 1/x => d2y/dx2 = -x^-2(dy/dt) + x^-1(d2y/dt2)(1/x).

Simplify the x^-1 & (1/x) => d2y/dx2 = -x^-2(dy/dt) + x^-2(d2y/dt2).

Sorry the formatting is useless in plain text, I could write it out later, but it'll be after the exam - and my handwriting a rubbish anyway so probably won't be any easier. Hope you can follow it as it is - if not just ask
12. Could they ask us to translate a half line like arg(z-4)=pi/6?

If so how would you go about doing this. Never seen it

Haha no time now

The book gives very limited examples and doesnt explain why you pick the values of theta like they do?
14. Whoever else is in London must've heard the thunderstorms. That is a taster of what is to come tomorrow.
15. Hoping for a maddeningly hard paper this year.

Well you can just find the equation of the line. probably depends on the question what the fastest/nicest way is

Jeez, that was proper movie style lightening. I have never experienced it like that before... our roof sprung a leak...
18. Can't sleep, going to be a zombie in this exam now. Why is it so hot
19. My Question 1: when the question ask to sketch the curve (and given equation) in which coordinate system we should do that? Polar or Cartesian? (E.g. Edexcel Text book 7c (pg 135))?
My question 2 : what happening with weather?!?
20. How you know? Have you seen the paper? If yes, thanks

Exam will contain proof of Maclaurin series
