You know (or should know) that $\int\frac {1} {x^2+1}\mathrm {dx}=\arctan (x)$. Let's try and get the integrand into that form. $$\int\frac {1} {x^2+9}\mathrm {dx}=\int\frac {1} {9 (\frac {x^2} {9}+1)}\mathrm {dx}=\frac {1} {9}\int\frac {1} {\left (\frac {x} {3}\right)^2+1}\mathrm {dx}$$.

29 maj 2018 · The integral can be solved by using integration by parts. The trick is to think of the function as a product of $\arctan (x)$ and $1$, both with respect to $x$. We solve the integral by choosing to integrate $1$ to $x$ and differentiate $\arctan (x)$ into $\frac {1} {1+x^2}$ which is easier to integrate: $$ \int\arctan (x)\cdot 1~dx = x\arctan ...
