Anyone know where I can get some really hard questions for this unit? I've done as many AQA papers as I can but I fear that that's comfort revising now after Wednesday's ordeal. I want to prepare for the literal worst.
What are solomon papers like and do they even exist for MPC4, I hear people go on about them all the time?
I don't understand how the AS core papers were similar to last year's standards then that abomination happened.
http://www.physicsandmathstutor.com/a-level-maths-papers/C4-solomon/ these are the edexcel Solomon papers but I find that the majority of the questions are relevant to AQA, also I have found that they have questions applied in different ways so they are pretty good to try and prepare for different styled questions
If you imagine you plot dy/dx on a graph, and call that y=f(x) then the maximum point will be where f'(x) = 0, or in other words, where d^2y/dx^2 = 0! (and I guess d^3y/dx^3 < 0...)
PLZ Someone help I think I am getting mental breakdown
I can't see to get the answer for this convert parametric into cartesian
x = t / 2t-1 y = t / t-1
Tricky - managed to get it down to (y/x) = 2 + (y/t) although not sure that helps...
When AQA hand out difficult parametric -> cartesians, they usually provide some base format of some kind (e.g. xy + y^2 + x^2 = k, find k) or similar. None of that given?

This might be a good shout then. I think the style of writing was part of the reason I got so phased with some of them I guess. Hoping this one isn't too bad considering I haven't got an A in core 3 now and at best I scrape As in core 4

same, I'm seriously hoping that this paper is reasonable :/

The answer is y = x/1-x I wasted this whole day to figure it out ...
