A Lagrange differential eq. represented as follows:
y = xf(y') + g(y')
Let y' = P
and after some fancy footwork;
dx/dP - xf'(P)/(P - f(P)) = g'(P)/(P - f(P)
Now, the link that I got this from states that this is a 1st ode in standard form.
When I attempt to solve such I end up w/the following integrand:
I have 2 questions. How do I proceed, and when I do, is this going to involve the natural log of a Fourier transform?
