1. Hi, after seeing how much people helped with core 1 to build the unofficial mark scheme, i thought it might be a good idea to make this thread to get a discussion going of how people are feeling about core 2.

This could be in the form of asking a question about something that you are stuck on/ need help with or it could be people sharing an unusual question / answer that they found and how to go about solving it so that it benefits others.

I would love to hear people's thoughts on this and good luck with core 2
2. Great idea to start this thread! I think I'll certainly be using it a lot today and tomorrow! I'm quite nervous at the moment because I feel under prepared but equally I'm feeling slightly more optimistic than in core 1 because I have a calculator

Thanks and yeah hopefully it will be useful to people. Any problems let me know and like i say if you find an interesting answer be sure to leave it here

Will do I'm just marking a past paper (Jan 2007)
5. Core 1 was vile. It was absolutely vile.
I can sense c2 being vile too because they changed the structure last year so I'm expecting many 5 markers, an awful q on logs, an awful q on inductive sequences, and tricky numbers to trip people up.
I really struggle with trig, I don't get the CAST diagram, someone please explain it to me😭😭

Can I suggest using a different diagram? I dont like the CAST diagram either it confuses me so much lol. Have you tried a normal trig graph? here look at this image. I can explain using this graph if you would like me to as well

What's an inductive sequence? Do thy sometimes use a different name for those? And yeah I wouldn't use CAST diagrams either, I use the standard trig ones
8. I just got 84% on that paper! Yay!

hey brilliant! I think get load of practice with the older papers to get used to the questions and then do the more modern ones as they require more skill / thinking.

Thanks I have a 2006 one and a 2008 one as well as 2013, 2014 and 2015

An inductive sequence is one e.g Un = 3n -5 and then they'll say like what is U7 or something. Although they can get much more tricky and require simultaneous equations etc..

Yeah look at the ones in 2014 and 2015 they killed me 🙃

Oh yeah, just arithmetic and geometric progressions, I've never heard them called inductive before but thanks for the explanation

yes but be careful cos they come under arithmetic chapter BUT do not have the same formulas. they are slightly different

haha i see what you are saying but if you write down all the info they give you and think about your options (e.g. simultaneous equations/subbing/equating or other techniques) then its not too bad at all :P

In terms of trig, how do you feel about using the y = tan x, y =sin x, y = cosx graphs instead of CAST, would that not be easier?
16. I was looking through a summary notes booklet and I'm a bit confused as to how they've done this worked example, wondering whether you guys could give me a hand:

They ask you to find all the solutions to the equation tan(2x-(pi/2))=tan(2pi/3) in the interval -pi </= x </= pi and they then get the new interval to be -5pi/2 </= 2x-pi/2 </= 3pi/2 but I don't understand how.

17. Considering the fact that I've studied A2 maths and further maths. I feel quite confident in the C2 paper. The only that still catches me are the Arithmetic and Geometric progressions. Does any body know an effective way of practic8ng these so they fit in my head.

Yeah sure what is the problem you experience with them when doing these types of questions?

Excuse that it was made in paint but this is what I would do, although i got a different domain to the one you gave me so idk if/where i have made a mistake either way this is the right method

I get confused with cos graphs 😒
