<http://mathforum.org/kb/message.jspa?messageID=7381491&tstart=0>The next
turn of the spiral might involve taking such functions and
making them methods of a Polynomial object.
Example framework:
http://www.4dsolutions.net/ocn/python/simppoly.py
So you'd have operator overloading and write things like:
>>> p1 = Poly( {2:3, 1:4, 0:5} )
>>> p2 = Poly( {1:1, 0:5} )
>>> p1**4
>>> p1 * p2
>>> p1 + p2 etc.
Once you have polynomials as "math objects" you might
compare them with other objects that also add, multiply
etc.
Questions about closure arise i.e. what operations might
take you outside the Polynomial type for answers, etc.
