Where the article explains it
Here is a known astronomical angular frequency, while and are constituents determined by fitting the expression to a record of observed water levels at that specific place.
The passage around this formula
Here is a known astronomical angular frequency, while and are constituents determined by fitting the expression to a record of observed water levels at that specific place. The division of labour is the whole trick. The frequencies are universal and can be built into gearing once. The amplitudes and phases are local and must be adjustable.
