Solution by Maple

Time used: 0.0 (sec). Leaf size: 23

dsolve([diff(y(x),x)=x^2+exp(x)-sin(x),y(2) = -1],y(x), singsol=all)
 

\[ y \left (x \right ) = \frac {x^{3}}{3}+\cos \left (x \right )+{\mathrm e}^{x}-\frac {11}{3}-\cos \left (2\right )-{\mathrm e}^{2} \]

Solution by Mathematica

Time used: 0.023 (sec). Leaf size: 30

DSolve[{y'[x]==x^2+Exp[x]-Sin[x],{y[2]==-1}},y[x],x,IncludeSingularSolutions -> True]
