Hi,(adsbygoogle = window.adsbygoogle || []).push({});

it is well known that a second order ODe can be transformed into a system of two ODEs through the transformation u=y', v= y.

Is the other way round possible? I mean, I have a system of 2 ODEs and want to transform it into a sucession on higher order problems that can be solved one after the other. Is this possible?

thanx a lot to anyone who can provide some insight!
