# C4 Integration

Announcements Posted on
Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. 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 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,
P____P

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