i have to integrate (ln x)(ln x)/ e^5t [in a variation of parameters problem] and have looked everywhere to see if Ln x multiplied by itself can be shortened to something like ln x^2 or some other reasonable thing but can't find such a rule anywhere. do i have to do this the long way with integration by parts? not even sure what to do with three things in integration by parts.(adsbygoogle = window.adsbygoogle || []).push({});
