Valery,

I think it's because of non linearity of the derivation of y(t).

There may not be y'(t)²- The terms of the higest derivation has to be linear. It's a typical Mathcad Problem.

Derive the Energy-Equation to the variable t, and all will be fine.

See attachement please.

Intsolve() is not dokumented in MP4.

How can that be?

Is it dokumented in MP3.1?
