Mathematica: cpu = 0.022503 (sec), leaf count = 23 $$\left\{\{y(x)\to c_1{e}^{-\sin (x)}+x{e}^{-\sin (x)}\}\right\}$$

Maple: cpu = 0.0 (sec), leaf count = 19 $$\{y\left(x\right)={\mathrm{e}}^{-\sin \left(x\right)}\mathit{\_}\mathit{C}\mathit{1}+{\mathrm{e}}^{-\sin \left(x\right)}x\}$$

Sage: cpu = 0.004 (sec), leaf count = 0 $$[(c+x)e^{(-\sin \left(x\right))},\mathtt{\text{linear}}]$$
