I see no reactance that performs this function.

Huh??? When the instantaneous source voltage is zero,
the instantaneous source power is zero.

So true.
Yet, there
is instantaneous power dissipation in every resistive
element in a circuit with a reactive component. Where
do you reckon that power is coming from? *

Fairly obviously, the equations I have presented show
that it comes from energy stored in the line.

Recall that
Pg(t) = 32 + 68cos(2wt)

For some of the cycle, energy flow is from the line
towards the resistor and the voltage source.

But this is not the energy in the reflected wave
which has the function
Pr.g(t) = -18 + cos(2wt)
and only flows in one direction, towards the source.
And it is this supposed energy that can not be
accounted for in the dissipation of the source
resistor.

It is apparent
that you are now just trying to pull my leg with your
ridiculous assertions. That's too bad. For awhile, I
thought you were serious.

Completely serious, I am.
