" Now to change the subject to something less boring, I have a question that will get us out of this quagmire.
    Setup:  I have a 1/2 wave length piece of 72 ohm twin lead attached to a 1/2 wave length dipole under pristine conditions.  Now I send two equal amplitude cycles of perfect sine wave into the twin lead.  What is the approximate SWR at the end of the first cycle and second?  This is a logical question, no Smith charts, Calculus, or higher math is needed for the answer. "

Pretty high.  The sine waves are not perfect because they started from 'nuttin; there is a high implied harmonic content at least for the first few cycles...and the Fourier interpretation for the Dirac Delta (impulse) function states that there are "harmonics" on all frequencies extending before the dawn of time and persisting out past the end of time.  Ouch!  My head hurts!

"Would that be European or African?  Laden or unladen?  What is the
humidity and air density?"

Rather than concentrate on matters of "higher" (derived from what those who done it were smoking at the time they dreamt it up) mathematics, I'd prefer to state that my favorite color is Blue...No!...Green!
