Subject: Re: Energy Transmission on a string.
Joel,
I think you are still missing the point. The maximumn angle of a
*perfectly* sinusoidal traveling wave with a wavelength of 1 m and
an amplitude of 1 cm is less than 4 degrees. And even this would
be an outrageously large angle for waves on a guitar string.

Given the constraint that it is truly sinsoidal, I don'tsee a way to avoid
the fact that some mass elements along the curve haveslopes of 45 degrees,
which IMO would invalidate the use of the small angleapproximation (at
least for that region of the string).
