What kind of wave is Asin(kx)sin(wt)?
Using trig functions, I've rewritten it as
Bcos(kx-wt) - Bcos(kx+wt)
So it sort of looks like it's a standing wave in that it's a superposition of two waves traveling in opposite directions with equal amplitude and wavelength, yet I'm unsure since it seems like the two waves would be canceling each other out perfectly.
So what is it?
