Edexcel FP3 June 2015 - Official Thread

Do I get a choice of doing s2 or fp3 first and if I do which one should I choose.

Depends on your school. In mine I am the only one doing FM and hence FP3 while others are doing S2 so naturally I do S2 first. If you can choose, go for S2; the easier paper first is a good rule.

If I get stuck on a "show that" question on reduction formulae/loci I'm just going to write down a bunch of working and then say "therefore *show that answer* (QED)" and hope for the best

Good luck to everyone!

My teacher who marks some of the papers says if there's a really long proof and he sees the right answer at the end, he'll generally just give all the marks. lol.

I got 68 last year. Hopefully I improve. I'm up at 1ish to cram till the exams. S2 cramming went well so hoping for an A in that.

68/75 or 68 UMS?

I prefer the 'hardest paper first' rule, hence FP3 at 9am for me :colone:

How do you know if a component of an eigenvector is independent (can be anything)? Would it just not appear in the equations when you expand?

Yeah. It can be anything if it isn't present in any of the equations you have.

I would think that you get something after doing the determinant usual way that indicates it. i.e 0lambda equals 0

yeah, if you can't deduce it from your equations then it's independent

So sinh(arsinh3) is 3, but how do you calculate sinh(2arsinh3)?

Either use sinh(2x)=2sinh(x)cosh(x) (and express cosh(x) in terms of sinh(x) using c^2 -s^1=1), or express arsinh(3) in terms of logs, and use log laws

Well line AB is r=(2,1,-2)+(1,1,-2)λ so you substitute this to r*(1,1,-2)=19 get t=2 thus r of B=(4,3,-6)
