    Rearranged slightly, the equation above it is

    \frac{\partial^2 \phi_\epsilon \left( x \right)}{\partial x} = \frac{2m}{\hbar^2} \left( V_\epsilon \left( x \right) - E \right) \phi_\epsilon \left( x \right).

    What happens when you integrate both sides of this equation from [itex]x = x_1 - \epsilon[/itex] to [itex]x = x_1 + \epsilon[/itex]?
