Cool Function
I've found a cool function: -|x|^(-|x|)
This function goes in waves over and under the point 0 of the X acces. If you go towards the negative or positive part of the X access the waves get smaller and it looks like in the end it'll be a straight line but it will only get smaller and smaller.
How many times can you subtract 7 from 83, and what is left afterwards? You can subtract it as many times as you want, and it leaves 76 every time. ~Author Unknown

Re: Cool Function
Hi pisquared;
What did you graph it with?
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Cool Function
I sketched it in a notebook with a pen.
You probably expected me to tell you a name of a computer programme lol...

Hi;
Hand methods can be misleading because they cannot sample enough points.

Re: Cool Function
I know, but I couldn't find a programme that doesn't cost money or actually works with the small details.
Maybe you can recommend one?

Re: Cool Function
Hi pisquared;
That function is actually rather well behaved. It is easy to numerically integrate it.

Hi,
The boundary curve is a superellipse: (x/4)^4 + (y/3)^4 = 1.

Re: Cool Function
Hi benice;
Thanks for the info. A superellipse? I never heard of that.
What is it?

Hey benice,
Wow! What programme did you use?
and bobbym,
I agree, it looks like a pink delicious hamburger!

Re: Cool Function
Hi pisquared;
Yes, perhaps a little on the rare side but there is an easy fix for that!
Hi benice;
Did not notice the link to the superellipse page.
Thanks for providing that.
