Thanks to John Denker for such a clear exposition. Very helpful.
In my case, we have V as a function of y, so it's known at all
points. We conclude that we know all we need to know, indeed. So why
can't Mathematica "figure out" how to do the numerical timestepping?
In other words, why can't it do whatever derivatives it needs to
solve the following problem?
This appears to me to be some sort of defect in the way Mathematica
is coded. Or am I missing something?
