# Edexcel 2016 Further Pure 3 - Model Solutions Watch

1. Hi,

I have probably messed up part 8c as I am terrible with these, Lemme know where I've gone wrong and I'll update it.

I thought it was a decent paper. Expect normal boundaries for C4 (A~62 IMO),

I intend to do the S2 paper, but that wont be tonight. These take hours to typeset and check. Probably do that tomorrow now that I have my freedon.

Enjoy!

3. Hey thanks man, what are your predicitons for the grade boundaries? I need about 75 ish ums and I reckon I got 63 marks (:
Thanks again.

Thanks again.
You'll get your 75, Possibly an A.
5. hey, in 4b) the integral should be 2e^x/e^2x+9
6. Hey,

Cheers for the solutions, I think I've spotted some issues?
3(a) the denominator should be
4 (ii) b, your result has a factor of 2 missing.

Not sure about your 8c, I typed the position vector into one of the planes, and it didn't give the value of the RHS for the plane equation. Probably should do it another method?

Apart from that, sounds fine, thanks for these once again.

For this part, I accidentally integrated 5coshx - 4sinhx instead of 1/(5coshx-4sinhx)

How many marks should I get? 2/5? (for changing my limits then subbing it back in at the end?) I really hope I don't get 0/5 omg I'm really worried someone please tell me

Yeah cheers, I'll update it tommorow. It's been a long day haha
9. For the last one I got (r-a)xb=0
Where a = (-j/5 - k) and b= (-11i + j -8k)
Can anyone confirm whether this is right?

Yes, that looks familiar to me.

The last part of questions 4, 1 / 4coshx - 5coshx should be 2 times what you have, so the final integral should be 2 times what you have.
13. Hey guys is (r - (-11/5 i + 0j - 13/5 k) ) x ( -11i + j -8k) = 0 correct for Q8c?

Also, how much would I get for Q7a if I wrote down In-In-2 in terms of the respective integrals and then combined them into one integral with (sin nx - sin(n-2)x)/sinx within the integration sign and then expanding sin(n-2)x and then just writing down the given answer in the next line?

Thanks.

full marks. That's what they wanted
