what is the "witch of agnesi" curve used for today?

Question

im doing a math project on maria agnesi, a famous mathematician, and she invented the "witch of agnesi" curve, or versaria. for part of the project im supposed to say how we use their mathematical contribution today, and i cant find it! please help!

Answer 1

I found the following:

The witch of Agnesi, a curve, has applications to real-life phenomenon, which has only come about fairly recently. The equation below where h=2a,

y=__h__ = __ha^2__
   1+(x/a)^2 a^2 + x^2

has importance with physicists. The equation approximates the spectral line distribution of optical lines and x-rays as well as the amount of power that is dissipated in resonant circuits.

It looks like it's also called the "Cauchy distribution", so you might find some other applications under that. I didn't find anything that was really straightforward.
