But he can't type it out?

You mean NDSolve[] can't solve ...

Mathematica can solve it. Every one can write
down a simple shooting method with a
few lines of Mathematica code.

If some one ask "how to solve .."
but he don't write down *what* he wish to
solve.

And the original poster asked for

Therefore it is very important that kind of diff. eqn's he
has.
