It is required to be continuous in the following text:(adsbygoogle = window.adsbygoogle || []).push({});

The book's reason why wave functions are continuous (for finite V) is as follows. But for infinite V, ##\frac{\partial P}{\partial t}=\infty-\infty=## undefined, and so the reason that wave functions must be continuous is invalid.
