\begin{align*} y^{\prime }-\frac {y}{t}&=\ln \left (t \right ) \end{align*}

Solution by Maple

Time used: 0.003 (sec). Leaf size: 14

dsolve(diff(y(t),t)-1/t*y(t)=ln(t),y(t), singsol=all)
 
\[ y = \left (\frac {\ln \left (t \right )^{2}}{2}+c_{1} \right ) t \]

Solution by Mathematica

Time used: 0.031 (sec). Leaf size: 19

DSolve[D[y[t],t]-1/t*y[t]==Log[t],y[t],t,IncludeSingularSolutions -> True]
 
\[ y(t)\to \frac {1}{2} t \left (\log ^2(t)+2 c_1\right ) \]
