20 / | | x | --------- dx | 2 | / 2 \ | \x + 1/ | / -1
$$\int\limits_{-1}^{20} \frac{x}{\left(x^{2} + 1\right)^{2}}\, dx$$
Integral(x/(x^2 + 1)^2, (x, -1, 20))
The answer (Indefinite)
[src]
/ | | x 1 | --------- dx = C - ---------- | 2 / 2\ | / 2 \ 2*\1 + x / | \x + 1/ | /
$$\int \frac{x}{\left(x^{2} + 1\right)^{2}}\, dx = C - \frac{1}{2 \left(x^{2} + 1\right)}$$
