___ \/ 3 / | | /x\ | x*acot|-| dx | \3/ | / 0
$$\int\limits_{0}^{\sqrt{3}} x \operatorname{acot}{\left(\frac{x}{3} \right)}\, dx$$
Integral(x*acot(x/3), (x, 0, sqrt(3)))

/ /x\ 2 /x\ | 9*acot|-| x *acot|-| | /x\ 3*x \3/ \3/ | x*acot|-| dx = C + --- + --------- + ---------- | \3/ 2 2 2 | /
$$\int x \operatorname{acot}{\left(\frac{x}{3} \right)}\, dx = C + \frac{x^{2} \operatorname{acot}{\left(\frac{x}{3} \right)}}{2} + \frac{3 x}{2} + \frac{9 \operatorname{acot}{\left(\frac{x}{3} \right)}}{2}$$
