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