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