    obviously simple to those with brains....... not me! how do you dooo that? :confused:
    It's just the standard taylor series result.
    f(x)=f(a)+f'(a)(x-a)+f''(a)\frac{(x-a)^{2}}{2!}+f'''(a)\frac{(x-a)^{3}}{3!}+...
    with a=1.
    Remember \frac{dy}{dx}=f'(x), \frac{d^2 y}{dx^2}=f''(x) and so on.

    Do you have formula book there? You don't really need to remember that thing.
    Just use f(x-1) = f(1) + f'(1)(x-1) + f''(1)(x-1)²/2! + ...
    You know f(1), f'(1)... from the equations they gave

    There is an absolute tonne of stuff for P6 in the formula booklet, including the Maclaurin and Taylor expansions and all the infinite series for sinx, cosx etc.. Incidentally, does anyone know what some of it is for? I don't have a clue what those matrices with trig in them are for :rolleyes:.

    Transformations such as rotation about the origin I think.

    hmm, you use expansions of sinx or cos when they ask you to expan a function with sinx or cosx (like expand f(x) = (x+ sinx)/(1-cosx)). It could be used to find the limit of the function, but I dont think they will ask about it.
    And the matrice with trig is for geometric transformation. You don't really need to use it. But I remember last year, the asked to describe the transformation, and that formula was useful for rotation through 45°. Don't get nervous of that

    I have a physics synoptics and two final economics exams tomorrow as well as a p4 exam before P6 on tues......on top of that i had just 4 weeks to go through p6 and no revision time.

    Despite all that i dont think that its actually that complicated, theres just a lot of stuff to remember!

    I did another mock P6 ! I did most of the questions!!! wheeeeeee!

    I wonder how I did... (my dad's marking it for me) :tsr:

    My parents seem to be magically repelled from anything even related to mathematics :rolleyes:
    Come to think of it, it seems nearly everyone I know in real life dislikes maths.

    I was intending to teach myself P6 next year. You're all doing a good job of putting me off!

    I think people dislike what they fear, and fear the unknown, and since, for most people, most of maths is unknown...
