    Trig Reduction Integral

    How do I solve this:
    (Latex keeps giving me errors, so forgive the crudeness here)

    \int(cos^2(sint))(sint)

    I know this problem is screaming substitution, but I cannot see what to do any help would be appreciated. Thanks.

    If it were \int {\cos ^2 (\sin (t))(\cos (t))dt} then a simple substitution is ideal.
    But I don't think it helps here.
    But I am thinking.

    Wolfram Alpha didn't give me any inspiration. Is that the whole problem?

    In exercises 21-54 use the techniques and reduction formulas necessary to evaluate the integral.

    44. int{ cos^2(sint)(sint)}

    I would wager that is a careless typo.
    As far as I can see, as well as Wolfram Alpha, there is no elementary primitive form.

    ok, I will contact my professor to see what he says, more than likely it is a typo, but will report back with any findings. Thanks for your time gentlemen.
