----------------
/     2\        
\1 + x /*atan(x)
$$\frac{1}{\left(x^{2} + 1\right) \operatorname{atan}{\left(x \right)}}$$

        2        
/     2\         
\1 + x / *atan(x)
$$- \frac{2 x + \frac{1}{\operatorname{atan}{\left(x \right)}}}{\left(x^{2} + 1\right)^{2} \operatorname{atan}{\left(x \right)}}$$
