    Boundary Condition causes DE to become Undetermined

    I have the following DE:

    h' + [(1+x)/x]*h = 0

    with the following BC:

    h(0)=A

    How do I apply this BC to this problem?

    Thanks

    The general solution is ...

    h(x)= c exp(-x)/x (1)

    ... and that means that the BC h(0)=A can be 'imposed' only if is A=0 and in that case is h(x)=0...

    Kind regards
