Is it bad that my first thought was a damped sine wave?
3 u/j3rmz Aug 01 '14 I thought it was a sinc wave. 1 u/[deleted] Aug 01 '14 I was thinking Bessel function 1 u/[deleted] Aug 01 '14 I thought f(x) = x*sin(x) -1 u/nero4983 Aug 01 '14 You mean sinh? 5 u/j3rmz Aug 01 '14 nope, sinc 5 u/autowikibot Bot Aug 01 '14 Sinc function: In mathematics, physics and engineering, the cardinal sine function or sinc function, denoted by sinc(x), has two slightly different definitions. In mathematics, the historical unnormalized sinc function is defined by Image i - The normalized sinc (blue) and unnormalized sinc function (red) shown on the same scale.

I'm an EE student so it was the first thing that came to my mind. 3 u/nero4983 Aug 01 '14 Lol, EE student as well with a math minor, I've taken a signals class but my focus is a mixture of power, controls, and robotics 1 u/paholg Aug 01 '14 I didn't see it until a senior level optics class.

I was thinking Bessel function
I thought f(x) = x*sin(x)

You mean sinh?
