Dear Peter:
Many thanks for your very lucid explanation! I am going to digest it along
with my Thanksgiving Day turkey. I especially appreciate the very first part
of your answer, in which you show how (and why) the strange example fails in
a simple case. I use this all the time in my own classes: "You might think
that this would be a great place to use Fourier series, but let's see why it
isn't." Students get a lot more out of seeing why a plausible but wrong
solution is wrong, than by having the prof say, 'We'll let u =tanh^-1 (y^2),
and then the differential equation looks just like a forced harmonic
oscillator' - Uh, how did you do that????

I'm very grateful to you.
