    Is there an exhaustive list of non-tables formulae anywhere? I don't want to get caught. Thing is, most people just say learn x y z formula and I get the feeling there's a list somewhere that says all the things you need off by heart (including nature of roots, forming quadratics, difference of cubes, etc.)

    Not really I'd say only what teachers or students themselves make out as study notes. I'll PM you a couple of bits I use.

    Examcraft? I got a B in that as well. Thought it was a bit easy, did the DEB one and got a C1... hope the real thing is more examcraft-like

    All I'm hoping for is to avoid financial maths in this paper, never truly got my head around why certain formulae can and can't be used at certain times

    I wouldn't mind a depreciation question to be honest. Or the question that asks you to turn a yearly interest rate in to a monthly one. i hope there is no ammortisation formula. i don't have a clue about that. ill take a look of it now though

    Amortisation is mostly used when dealing with loans and paying stuff back over time. It can be used for other questions too but that's what you use it for mostly.

    `F=P(1-i)^t
    F is the future value of something (it's lower than the present value for a car or something like that)
    P is the present value
    i is the rate of depreciation and t is the time(or compounds)

    Or in other words it's the opposite of adding interest, you are taking interest off the value.

    This paper restored my faith in God (well not really, but if there is a god, he works at the SEC!!!)

    F***ing beautiful paper.

    Jane98: PRACTICALLY NOTHING. THE QUESTIONS WERE ALMOST INTUITIVELY SIMPLE. THE BEE QUESTION COULD BE DONE BY A 10 YEAR OLD.

    That was easier than I anticipated.

    Trouble now is, paper 2 is gonna be gruesome.

    I suck at paper 2 anyway, so no love lost there. I just hope it isn't marked too harshly. lol at how much I stressed over financial maths!!!

    By the way, was the acute angle 87 degrees?

    How did you guys find the angle?

    I TanQ = rate of change of slope (diff twice), then tan inverse to find the angle.

    Yeah me too, tan inverse of the slope?

    That's the first I've heard of Pythagorean triples, bit annoying.

    LOL! That's that sorted then:D

    I forgot to set my calculator to radians so I had to convert it myself.
