$\frac{d u}{d x} = c u + x^{2} .$
$\frac{d^{2} u}{d x^{2}} - x \frac{d u}{d x} + u = 0 .$
$\frac{d^{2} u}{d x^{2}} + ω^{2} u = 0 .$
$\frac{d u}{d x} = u^{2} + 1 .$
$L \frac{d^{2} u}{d x^{2}} + g \sin u = 0 .$
$\frac{\partial u}{\partial t} + t \frac{\partial u}{\partial x} = 0 .$
$\frac{\partial^{2} u}{\partial x^{2}} + \frac{\partial^{2} u}{\partial y^{2}} = 0 .$
$\frac{\partial u}{\partial t} = 6 u \frac{\partial u}{\partial x} - \frac{\partial^{3} u}{\partial x^{3}} .$
