In other words (read carefully), the complex
terminating impedance whose value is Z0 is
equivalent to an *infinite extension* of the coax
whose complex value is Z0. This is the "clincher".

Exactly, Bill! And with that, you don't need any equations. You only
need to realize that if you cut a line which had no reflection on it,
you can weld it back together without introducing reflections
(assuming you do a perfect job restoring it to its original state).
That should be obvious and easy to grasp even for a math-o-phobe.

And thanks to Roy for taking the trouble to actually go through the
algebra and post it. I honestly hoped that S. would do that, and
still cling to the belief that there may have been a lurker or two who
also did it.

Cheers,
Tom
