    Because e^x differentiates to e^x, rather than e^(x-1).

    It's the derivative, not the differential.

    ah so would it be correct for me to say the first differential?
    for \dfrac{\mathrm d y}{\mathrm d x}?

    sounds awesome cheers Zacken, i can use this on my personal statement as part of the "what inspired you to do maths" part >.>
    in any case

    does that lim thing mean where the change in x is going towards 0???
    I may need to post back here a few times aswell to ask about a few other things i may not understand ^-^

    You might be better off not reading it if you don't know what a limit is. :-P
