    Calc II: Quick Question! Integration by Parts.

    I cannot do this problem:

    e2xsin3xdx

    It is part of the homework for "integration by parts" assigned by my professor that is due tomorrow, but I'm wondering if she mistakenly assigned it. There is a note in the textbook for this problem that says graphing calculator required and we don't use calculators. Is it possible to work this one out without a calculator in less than a million steps? Am I doing something wrong?

    Apply integration by parts two times and then you'll have to make a substitution, let  \int e^{2x} \sin(3x)dx = I.
