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

1. Could somebody explain how the method of differences worked given one of the terms wasn't a fraction?

I wrote them out in like 4 different ways and couldn't get them to cancel out..
2. (Original post by target21859)
Yeah everyone went on about that question after. I thought it was just C4?
I meant I messed up so bad in that question that I didn't even have e2x sinx anywhere fun times

Phew, thank you, I had pi/24 13pi/24, 25pi/24, 37pi/24, Is that Ok then?
I assume so. You could probably work it out by looking at old past papers and mark schemes with the same thing.
4. (Original post by target21859)
The second value for theta should be 13/24 not 13/14 typo?
yeah that's still different to what I got so would still like to know how you did it? I'm awful at complex numbers.
5. (Original post by AlexFrangos)
What did you get in the last part of the last question?
3rt(2)/2 + rt(58)/2 ?
6. (Original post by sweeneyrod)
How were you supposed to do Q4? I did i.b.p. twice to get I = something + (1/4)I, but I don't think that's on the A-level syllabus.
That was the intended method, yeah. And that's definitely on the A-Level syllabus. It's IBP and algebra.
7. Boundaries are gonna be a lot lower than normal imo

I got exactly the same as you. I labelled them as z1, z2 etc. respectively then just wrote z1 next to their appropriate location on the argand diagram and did a line from 0 to the approximate cross.
Hope it's right, I lost at least 15-16 marks

Take the r-3 out of the sum and evaluate it FP1-style, then do m.o.d. on the fractions.

I = something + 4I

but yh

I mean, it's common sense. And all knowledge required to do this question is on the syllabus
11. you can do q4b like http://i.imgur.com/sNc63M1.jpg

3rt(2)/2 + rt(58)/2 ?
Found the same !!!
13. (Original post by Nijuuninichi)
Same. I don't feel like it's looking good for FP3 either, I feel like I should start revising for it now.
Well good luck. I've got M2 left so hopefully I can smash that
14. Got 60-67, inclined towards 67.

If so hopefully 67 is an A*
15. Is it just me - or was 4c a lot easier than first glace - I got it but in a really complicated way

I think i got 70/75 - UMS predictions??

I saw that it was going to be that and couldn't remember the formula for the sum of r. Ugh.

What did you get in question 2 and in 2nd order differential equation?
18. (Original post by Zacken)
That was the intended method, yeah. And that's definitely on the A-Level syllabus. It's IBP and algebra.
In C3/C4? I don't think our class learnt it in any case.

20. Does anyone remember how many marks q1 was?
