Solution by Maple

Time used: 0.0 (sec). Leaf size: 5

dsolve([diff(y(t),t)=2*t*y(t)^2/(1+t^2),y(0) = 0],y(t), singsol=all)
 

\[ y \left (t \right ) = 0 \]

Solution by Mathematica

Time used: 0.003 (sec). Leaf size: 6

DSolve[{y'[t]==2*t*y[t]^2/(1+t^2),{y[0]==0}},y[t],t,IncludeSingularSolutions -> True]
 

\[ y(t)\to 0 \]
