    Hi guys, i was wondering whether some of the genuises (or simply people who are cofident on C4) could help a lot of us here........

    Is there any chance that x number of individuals could start summary threads of the chapters of C4?

    C4 Algebra Thread
    C4 Coordinate Geometry Thread
    C4 Binomial Expansion Thread
    C4 Differentiation Thread
    C4 Vectors Thread
    C4 Integration Thread

    Obviously the last two threads are the largest and may require more than one person? I would volunteer but its myself who would really be happy to see this happen in time for next tuesday. It would also make it easier for questions to be asked in the relevant section and to be answered quicker.

    I think that there would be substantial repping available here for whoever can contribute.........

    Please post here who is prepared to do what..............

    Many thanks

    That would be good.

    I am not saying I will do any of them (yet) as I need to work out how much I need to do for my personal revision first.

    INTEGRATION IS HARD.

    ah cheers!

    Now we just need some more voluteers, i think this would help many of us...

    This is surely a good idea, but all these sections are so densed, the first 3 chapters need not be summarised, as theres already some good (revision/summary) threads and links for them, I'd recommend someone just post links and threads for these.

    As for the last 3 sections, these are good to summarise. Differentiation and Integration should not be thought in isolation, rather put into the category of Calculus. And a full summary on vectors is a really good idea. :rolleyes:

    vectors is the only section i need help on, other than that the book is quite good.

    I would say forget the Binomial (as you say) but roll some of the parametrics chapter into the differentiation / integration section. After all the chapter has got diff ( (dy/dt)/(dx/dt) ) and int ( ∫y(dx/dt)dt ).

    C4 Differentiation
    "Implicit Differentiation"
    Use of the chain rule:
    i.e. fact that dy/dx=dy/dy.dy/dx
    e.g. y=2y2-x
    'diff. wrt x:' 1.dy/dx=4y.dy/dx-1, then rearrange.

    Parametric Equations
    Uses fact that dy/dx=(dy/dt)/(dx/dt)
    ...unless can deduce cartesian equation (which usually requires a form of pythagoras' theorum)
    Also dy/dx=1/(dx/dy)
    EDIT: It turns out there's not all that much diff. in C4
    Someone might like to do these 2 in a bit more detail then..

    Oh well I learnt from P3 so I don't know
    In that case what diff. is left for C4??

    Its just best to emphasise all the rules from previous modules
    occasionally, some exam boards ask questions from previous modules, people loose many marks by not remembering previous stuff. Yet I haven't encountered this with Mei (I think)

    Just the implicit and parametric stuff (but this could be done with C3 knowledge).

    Is it correct that all P3 circle geometry has been put in C2? There's none in C4, right?

    Ive got some excellent notes on vectors ill try and scan them in (there on yellow paper) then post them, got them of my teacher helped me no end with what is themost difficult topic in c4 for me personally.

    Hey thanks

    I just hope we all get A's or B's come August, im still going to "tidy-up" my A Level Maths in Jan 2006 whilst im at university just to get the A garde anyway!

    Yes.

    C4 Only Covers:
    -> Partial Fractions
    -> Parametric Equations
    -> More Advanced Binomial (first covered in C2)
    -> Implicit Differentiation (including y = ax)
    -> Vectors (all)
    -> Integration (all, C3 has none)

    when i was looking at the C2 formulae in the booklet, it included the C4 formula for n<1

    I think the formulae booklet is the same throughout every math exam, its not specifically for C2 but for all the modules (for me anyway)
