Sinc Function Curve

 From:  bemfarmer
Attached is a quick script to create the curve known as the Sinc Function.
See Wikipedia.
The local maxima and minima of the unnormalized sinc function intersect the corresponding cosine function.

What is it good for? :-)
a. Not Much
b. Hats
c. ?

Noticed that a revolve on the x-axis only does one section. Same with sine function.
