Hi Simon, thanks for your reply. Thanks for your suggestion, but I think I'll stick with the integration by parts method, since I have convenient expressions for F(m) (\frac{d}{dm}D(m)) that I will need to integrate. Once again, thanks for the help.

My end goal is to solve for G(m) in terms of the other functions, but first I have to solve the DE : \frac{d}{dm}[F(m) G(m)] = (\frac{d}{dm}F(m)) D(m). What I've done is to say (using integration by parts) F(m) G(m) = F(m)D(m) - \int F(m) (\frac{d}{dm}D(m)) dm. This is one method I...

Nonlinear DE (with e^t) ? Good day forum, I have this wonderful DE : dx/dt = [a - f '(t)]x + (b + d(c^t))(x^2) - 1 with, t \in [s,T] x(T) = 0 a, b, d & c are constants. f(t) = g + h(k^t) , where g, h & k are constants (but I think specifying this is of no...
