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!
