... + V (x) ψ(x) = E ψ(x) 2m As a linear second order differential equation, we must specify boundary conditions on both ψ and its derivative, ∂x ψ. As |ψ(x)|2 represents a probablility density, it must be everywhere finite ⇒ ψ(x) is also finite. Since ψ(x) is finite, and E and V (x) are presumed finite ...
