How did he know that?". It is basically the harmonic oscillator. After a few years' study of physics this kind of stuff becomes obvious. I would probably use A exp(-kx) + B exp(+kx) instead, because complex exponentials are in general easier to work with than sines and cosines.Petra Axolotlhttps://www.blogger.com/profile/06597951512037995047noreply@blogger.com
