    Ok, i have decided not to post many integral question like i did before but my keen interest in calculus makes me approach these questions almost everyday and i happen to stumble upon hard questions(at least for me), but i must say this integral isnt at all "tedious", its rather interesting i think, so i would appreciate any hints, (not answers) would be great. Thank you




    i do sense some sort of generalization(obviously) for any powers of "x". Can anyone help me out??

    Try induction on n and integration by parts.

    Use integration by parts than apply a reduction formula.

    Very simple.
    Simply integrating by using integration by parts.

    If im not asking too much, why dont you show me how you would try this? I have actually solved it today,but actually for this question the answer isnt in the book, so i might never be sure if im right.

    You have had several, duplicative, suggestions. Now work it out for yuorself. Yoou should, by now, be able to check and verify your work. Real problems do not come with answers "in the back of the book."

    Use the fundamental theorem of calculus to check your solution.

    The thing is I get a factorial in my answer, and that seems weird. I ususally dont get in most of my integral questions
