Regarding Hurricane cos(x):
- If Equator is the x-axis and the y-axis goes through the Prime meridian of Greenwich it would be possible to say if this was a true cosine function hurricane.
- A cosine would be 1 (the maximum value) at x=0 (i.e. the maximum value would occur under Greenwich), whereas a sine would be 0 at x=0.
- If it had been a basic cos(x) without any constants added, then it should have been centered along the equator instead of as it is - ranging from about 5.5° to 9.5° north latitude.
- But if the formula was of the form a*cos(b*x)+c with a, b and c given constant, the wave could move to the center of this range with c=7.5°. With the constant a=2° the wave would move between the max and minimum of the range, and then b could be chosen to make the wave length fit with the path shown in the map.
