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!
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

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
