When you use a pulse, p(t) = v(t) * i(t) shows the pulse going
by and coming back too, if it reflects. But for that, you have to
look at things in the time domain, something a number of readers
here refuse to do for continuous sinusoidal excitation. When you
look at continuous sinusoidal excitation in the time domain all
the information you need about power is provided without having
to resort to Pfwd and Prev.

Yes, but those steady-state shortcuts often lead to a distorted
view of reality. Exactly what magic happens at the instant when a
system goes from the transient state to steady-state?
