There are several situations I don't know how to solve:(adsbygoogle = window.adsbygoogle || []).push({});

integral of (lnx)/(x^2) dx

integral of e^x(cos2x)dx

integral of ln(1+x^2)dx

I have a quiz tommorow, and after looking through some notes, this is what I couldn't understand.

Please help! thanks.
