    Hello again TSR,
    I came across this method of a integration.

    If youve not seen it, it is basically another form of integration by parts, but it is a lot quicker to do if you have something like  \int e^{x} x^{n} dx and as n gets larger, integration by parts gets pretty boring and long to do.

    Granted that n wont be anything above 3 or 4 in C4, I was wondering if I could use this instead of by parts?


    Thanks,

    You could use it. It's not any different to IBP. That said, I can't see it being espcially useful in C4 and higher up, reduction formulae are much more useful.

    Reduction formuale are very useful
    I won't lose any 'M' marks, would I?

    Yes, it works well. It is exactly integration by parts, just expressed in a tabular form.
