$$y^{″}(x)-\cot (x)y^{\prime }(x)+y(x){\sin }^2(x)=0$$ ✓ Mathematica : cpu = 0.0370826 (sec), leaf count = 19

$$\left\{\{y(x)\to c_1\cos (\cos (x))-c_2\sin (\cos (x))\}\right\}$$

✓ Maple : cpu = 0.164 (sec), leaf count = 15

$$\{y\left(x\right)=\mathit{\_}\mathit{C}\mathit{1}\sin (\cos \left(x\right))+\mathit{\_}\mathit{C}\mathit{2}\cos (\cos \left(x\right))\}$$
