Tried to solve numerically: http://groups.google.com/group/sci.math/browse_frm/thread/248f76d024c1ac57/0bba983777a07bc9#0bba983777a07bc9 thus: EQ= { f'[x] == f[f[x]], f[0]== 1} ; NDSolve[EQ,f,{x,0,2}]; But gives an error. NDSolve::ndnum: Differential equation does not evaluate to a number at x = 0. Also does not work even with other f[0] values. Any way to do that?
