==========================
The following short question is adressed to all contributors to this
newsgroup who feel impelled to bolster their lack of self-confidence by
dragging in the chapter and verse of their favourite worshipped authors and
Gurus, most of whom nobody has ever heard of and highly unlikely ever to get
their hands on.

How do you know that?

I multiplied v(t) and i(t) in the forward and reverse waves and added
them as a function of position to get the instantaneous power at each
point along the line. Then I integrated to find the energy. As I
mentioned in the part of the posting you excluded from your quote, I
discovered that I hadn't evaluated the constant of integration.
Somewhere along the line, I got sidetracked, and didn't want to get
sucked into the interminable argument going on (which I see I've started
up again -- my sincere apology to all), so didn't go back and clean it
up. I had, however, reached the same conclusion as Magid, so apparently
the constant was zero, or didn't impact the results. Magid follows the
same process, although I haven't yet followed it through completely.

You've now heard of Magid, and you can very likely find a used copy on
the Internet for the price of a couple of bottles of mediocre Pinot Noir
in much less time than it would take to drink it (unless perhaps you're
a speed drinker). You could get your hands on one with even less effort
than I've taken -- I had to walk a few blocks, while you can do it all
from your easy chair, only having to rise and face the Sun when the
postman comes with your book.

Shoot, you can even get it from the same store where I got mine, if they
have another copy just now. http://www.powellsbooks.com.
