Hi, do you remember the equation for question one (e.g the fraction that had to be split) OR the two separate fractions that then had to be used for the binomial please? I just want to have a go at it again! Thank you!


(19x-3)/(1+2x)(3-4x)
q.4 part a was 4 marks, hope that helps

they'll be low but that low?



The June 2011 paper which wasn't as hard as today's paper, was 51 for an A in C4.
Anyone remember the question 3 with the sin = 1/root5 thing, what was the wuestion and what angles were we given?

1)

C = (0, 10/3, -5/3) D = (4, -10/3, -1/3)


omg i got C but i scribbled it out LOL...

none, i did that too, i stated that costheta is 13/35 and then found theta


Yep, on the mark scheme there will be a line with costheta=..... and ISW (ignore subsequent working) next to it. So if they see costheta=... they give you the marks.
How many marks would be lost if you got lambda=1 and mu=-1/2? I'm thinking my simultaneous equations are probably slightly wrong becuse I missed a sign somewhere. Luckily I subbed in my lambda for the point of intersection though

Pretty sure I got the same values as you and I can't see where we would've gone wrong, as I went over this again and again and my equations all worked out with these values

June 2014 was 59 for an A* and I believe this paper was more challenging.

anyone got an unofficial mark scheme for it

Wait I got that too. Are people saying its wrong?

It looked like some people got other values for lambda :/ unless I'm getting confused with questions haha

I'm pretty sure I got those values too. I subbed both my lambda and mu into all three simultaneous equations and they all worked so I think we're right.
Plus my coordinates seem to match the unofficial mark schemes scattered about


Lol, people are still making these even if the exam is easy.

jk. I didn't even attempt the differential question.
