x - 2*--(y(x))*y(x) + x*--(y(x))*cos(y(x)) + sin(y(x)) = 0
dx dx
$$x \cos{\left(y{\left(x \right)} \right)} \frac{d}{d x} y{\left(x \right)} + x - 2 y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} + \sin{\left(y{\left(x \right)} \right)} = 0$$
x*cos(y)*y' + x - 2*y*y' + sin(y) = 0

2 x 2 -- - y (x) + x*sin(y(x)) = C1 2
$$\frac{x^{2}}{2} + x \sin{\left(y{\left(x \right)} \right)} - y^{2}{\left(x \right)} = C_{1}$$
