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