I have the question Evaluate [tex]\int_{Pi/4}^{Pi/8}_cot^2{2x}dx[/tex](adsbygoogle = window.adsbygoogle || []).push({});

So integrating this should (I hope) give [tex][\frac{-1}{2}cot{2x}-x][/tex] for those limits.

But I have never evaluated the cot integral before, I know that cotx=1/tanx. Do I substitute this identity in and work from there?
