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.
