With some algebraic steps the DE becomes...

(1)

... which is linear and can be solved with 'standard approach'...

Kind regards

You could always do a series solution method!

If you had some I.C's then a numerical method like runge-kutta?

The substitution renders the equation separable:

and hence if we have

then we arrive at

Another one is by using inspection.

... (1)

Your equation is ready for integrating now.

Actually, equation (1) is equivelant to the last equation in Ackbeet's replay. - Feb 11th 2011, 02:36 PMGeneral
