I was trying to achieve a universal formula for a bichromatic wave surface elevation consisting of two waves with different amplitudes. There is a universal formula for a bichromatic wave surface elevation with the same amplitudes:
eta = H/2cos(om1*t) + H/2cos(om2*t) = H * cos((om1-om2)/2 * t)...
Homework Statement
Superposition of two cosine waves with different periods and different amplitudes.
Homework Equations
This is basically:
acos(y*t) + bcos(x*t)
The Attempt at a Solution
I looked at different trig functions but it seems it is not a standard solution. I've found solutions...
