So you have (1/x)dx = -(1/(vlnv-v) )dv= -1/(v(lnv-1)

Now the integral of -1/(v(lnv-1) is -ln(lnv - 1)

Then proceed accordingly, hope I helped :) - December 2nd 2011, 11:08 AMalexmahoneRe: Homogeneous ODE

In my example differentials dx and dv are in denominator:

I'm having trouble applying your formula in this case. Can you please clarify further? - December 3rd 2011, 03:13 AMProve ItRe: Homogeneous ODE

Yes, that is the idea. However, just in case an overview helps...
