Hello !
I encountered a problem, trying to numerically solve a differential
equation.
My equation looks like:
A y''[x] - B y[x]' + C Exp[-Dx] == 0
with boundary conditions: y'[0]==0 , y'[E]==0
All constants A to E are known.
Mathematica complains, that the equation is not linear. But in the
online documentation I saw many examples of nonlinear differential
equations, which all work fine. What is the difference between the
examples and my equation ? And is there a possibility to NDSolve my
equation ?
Any hint on this would be of great help to me.
Thanks a lot,
Ronald
