E95 -- De aequationibus differentialibus, quae certis tantum casibus integrationem admittunt
(On differential equations which admit integration only in certain cases)
Euler starts with a second-order linear differential equation with simple, rational coefficients and figures out which
cases of this quantity, divided by infinite sequences, produce a quotient that can be integrated. Then he derives a first-order differential equation out of the given equation and gets a new integrable equation in this way. The Riccati
differential equation appears as a special case.
