converting this notebook to a python script

When you run this notebook it will pop up a simple plot. You can save this notebook (.ipynb file) as a python script and run it from the unix command line as follows:

python mymath.py

or if you edit this file and as first line add

#! /usr/bin/env python

and make this script executable

chmod +x mymath.py

you can then run it as follows:

./mymath.py
