How to integrate (x+\tan x)^2
https://www.quora.com/How-do-I-integrate-x-tan-x-2
Open the brackets. You then have three separate integrals. The first \int x^2dx is simple and equal to \frac {x^3}{3}. The second \int\tan^2xdx is also simple if you remember that \frac {d (\tan x)}{dx}=1+\tan^{2}x ...

https://math.stackexchange.com/questions/1652236/deducing-the-series-expansion-of-arctanx2-via-the-series-expansion-of-ar
This approach is perfectly valid. When we have a series \sum_{n=0}^\infty a_nx^n then replacing x\mapsto x^2 we get \sum_{n=0}^\infty a_nx^{2n}=\sum_{n=0}^\infty b_nx^n which is a power ...
