$$y^{\prime }(x)=\frac{\sin \left(\frac{y(x)}{x}\right)\csc \left(\frac{y(x)}{2x}\right)\sec \left(\frac{y(x)}{2x}\right)(2x^2\sin \left(\frac{y(x)}{2x}\right)\cos \left(\frac{y(x)}{2x}\right)+y(x))}{2x}$$ ✓ Mathematica : cpu = 0.109961 (sec), leaf count = 19

$$\left\{\{y(x)\to 2x{\cot }^{-1}\left(e^{-x-c_1}\right)\}\right\}$$ ✓ Maple : cpu = 0.21 (sec), leaf count = 48
