    sin(5x+3x) =...
    sin(5x-3x) = ...

    or if you want to show off integration by parts twice (loop)
    then how do you integrate that?

    Do you want a cookie bro?
    No. Full UMS would be nice though for 588 overall.

    How have you been doing on the past papers?

    What method do they use?
    They used IBP, but without expanding. I've just had a read of the examiner report though and it seems that either method was acceptable which means that It was probably just a mistake on my part (although I don't understand why they wouldn't mention it on the mark scheme? =/)

    I don't know what the difference is. Just use integration by parts

    Do you think they could ask integrals like these? these are trickier than normal

    Do you not like cookies? And I'm not taking C4 this year. I did it last year because I do FM, so I did maths A level in one year. I just came on here too see if anyone needed any help

    the one that the other chap asked for like sin3xcos4x I think are not likely under the current specification, because they involve more trigonometry than integration.

    the rest are possible but still unlikely
