Usage notes on sinh()/()/cosh()• When we started to deploy instruments indeep water we discovered that the wavesalgorithm was slowing down significantly(exponentially) with depth.• After some investigation we discoveredthat the slow-down was related to thetranslation of horizontal and verticalcomponents of orbital velocity to surfacedisplacement.
Usage notes on sinh()/()/cosh()• The equations in use are of this form:F = cosh(k(h+z))/sinh(kh)• When h gets large the numerator anddenominator can be on the order of 10 250 ,or greater (or even NaN or Infinity)• What we are after – the ratio of the two,may have a small value – such as 20.
