\begin{align*} y^{\prime \prime }+\left (1+\frac {2 \cot \left (x \right )}{x}-\frac {2}{x^{2}}\right ) y&=x \cos \left (x \right ) \end{align*}

Solution by Maple

dsolve(diff(y(x),x$2)+(1+2/x*cot(x)-2/x^2)*y(x)=x*cos(x),y(x), singsol=all)
 
\[ \text {No solution found} \]

Solution by Mathematica

Time used: 0.000 (sec). Leaf size: 0
