... Continuity of ψ(x) and its derivative What about at x = ± L/2? The left side of the equation, Eψ(x) or (E − V0) ψ(x), is finite; but the right side is not finite unless both ψ(x) and its derivative dψ(x)/dx are both continuous. Therefore, the solutions of the time-independent Schrödinger equation m ...
