This is a 3u question, but I am confused as to how I can do this without 'partsing' it.....

I guess it would be a substitution with probably letting u=tanx

I'm not sure though otherwise

$\frac{2x\sin^{2}x}{\left(1-\sin^{2}x\right)^{2}}$

Good ideas however you still have to do IBP as there are two variables.
