Hello! I do ccea further maths, in northern ireland ...so im in year 12 here, but it's the equivalent of year 11 in England...moving on from the blabber..
I have a maths mock on this thursday and it's everything we have covered in pure maths excluding logs(we havent finished it yet). So i was doing one of the old 'Additional Mathematics papers for pure Maths(PAPER 1) of May/June 2005 by CCEA.
I came across this deadly question, can anyone help me out please? Mock on thursday.
I can't find the mark scheme anywhere on the interweb
and can you tell me whereabouts i went wrong please because i only got up to the differentiation part and got dy/dx= 2ax-5, with b=-1, i don't know what a=...c=4. It's mainly just part (i) that i got stuck on, which prevented me from doing the rest of the question! Please help! I have posted this exact thread on the Maths Exams forum.
