$\int (x^2+1)/(x^4+1)\ dx$

Integration by parts, the cases when it does not matter what $u$ and $dv$ we choose.

$\int \sec^3x dx$ in disguise

Methods for choosing $u$ and $dv$ when integrating by parts?

For continuous 1-periodic f. $\int_1^{\infty}\frac{f(x)}{x}dx $ converges.

Solving integration by parts $\int\frac{xe^{2x}}{(1+2x)^2}\,dx$

Per partes integration: $\int x^2 \ln x dx$
