Hello to everybody I'm trying to integrate this ODE but I don't know how: f'''+a*f*f''=0 where a is a parameter. With the boundary conditions f(0)=0; f(-inf)=1; f(inf)=1. I had thought about using a shooting method but I don't know how to apply it with these boundary conditions. It would be nice if somebody could help me or give me a reference where I can find it( I have already looked for it in some books but I find nothing). Thank you. Michujo.
