I know I was so happy when I go that, and the simplified trig identity, one right.


I got sin^2x , But that's all I wrote. I knew it had something to do with sinx/cosx , But I didn't know how to write it down lol.

Is that what you got? Sin^2x?

For the subject of the formula thing did anyone get:

K = L^2+P/4t


Damn I'm pretty sure I got K = (L+P)^2 / 4t

I had that but then took out the brackets and put L^2 without P being squared

PHEWWWW

Hopefully you get 1 mark or maybe even 2/3

What was the height of the label in question 12 paper 2 I think? I used the Pythagoras theorem and kept getting 14 something, but that was obviously wrong since the diameter was 13.2 cm.

I got 11.2 m or something like that. You had to half 9, so you'd get 4.5 then use pythagoras.

So a^2 = 6.6^2 - 4.5^

Then whatever answer you got just add it on to 6.6. That's what I done anyway, not sure if it's right so don't quote me on it lol

15/40 (being generous too)

I've done worse in paper 2 than I thought at first, reading people's answers here... I need 30 to pass and I've done so many questions wrong, there's just no way :frown:
Paper 2 answers are out, go to https://twitter.com/SumTeacherWeb

How did you get that? I got 106. I got the other two angles in the triangle as 37, added them and took them away from 180.


I got 106 too!

Yeah, I misread the cone volume question to 2 d.p not 2 s.f, I had plenty of time to check over the paper... How did I not notice :frown:

I got the final answer before it was supposed to be rounded so hoping for 4/5
