Method of integrating factors

delve

Is there a method of integrating factors for differential equations of power 2 or higher?

g_edgar

"power" in the sense of second or higher derivatives? Probably not. Integrating factors are for first-order DEs.

kosovtsov

Integrating factors are are suit for any order ODEs, see, e.g.,

Knowing integrating factor allows to reduce the ODE order.
