# Talk:453: Upcoming Hurricanes

I wonder, is there a reason why Randall chose cos(x) over sin(x)? Is there a y-axis somewhere on the map? Not that it matters; just curious... Bobidou23 (talk) 23:24, 22 September 2012 (UTC)

cos(x), sin(x), they're the same thing, plus or minus pi/4... -- IronyChef (talk) 02:57, 23 September 2012 (UTC)

If something is less than satisfactory, you are fully welcome (and even encouraged) to edit the explanation to be better. lcarsos (talk) 06:37, 28 October 2012 (UTC)

Whoever said hurricanes cannot form within 5 degrees of the equator was wrong... It is not likely but it is possible. http://en.wikipedia.org/wiki/Cyclone_Agni http://en.wikipedia.org/wiki/Typhoon_Vamei 152.2.128.198 14:36, 5 November 2012 (UTC)

This title-text seems strangely prophetic after Tropical Storm Sandy in 2012. -- 107.204.46.198 (talk) (please sign your comments with ~~~~)

Yes, I agree. David1217 (talk) 17:18, 19 January 2013 (UTC)
There is more to win from predicting something that is going to happen than there is to lose from predicting something that doesn't happen. Tharkon (talk) 19:30, 1 December 2013 (UTC)

Has anyone any idea what the "&" symbol is about in Hurricane Where-The-Hell-Is-Bermuda? 141.101.97.215 12:32, 13 May 2014 (UTC)

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.

There is no reason to assume the axes are on the meridian and equator. Tharkon (talk) 02:41, 7 September 2014 (UTC)

The details for Hurricane cos(x) mentions a trivia section, which is not present in this article. Just some random derp 17:41, 21 June 2015 (UTC)

I was about to post the same comment but then I decided to read these first. 108.162.237.158 07:52, 25 June 2015 (UTC)
