Cecil,

Why would anyone try to prove that the basic math of adding sinusoidal
functions is incorrect? To the contrary, you are the one who insists
that a standing wave and its constituent traveling wave components are
somehow different and unique. No one denies the simultaneous existence
of standing waves and traveling waves.

Isn't superposition wonderful!
