Hi All,
I am trying to get the Real root as shown below and keep getting a
NameError. Any suggestions?
I am using python 2.6.2 and sympy 0.6.5.
The solution should be:
a=0.31883011387319
>>> from sympy import Symbol, nsolve
>>> a=Symbol('a')
>>> f1=1/(0.001+a)**3-6/(0.9-a)**3
>>> print nsolv
Hi,

Thank you for this - I am studying it and it definitely has some of
the flavour of what i'm thinking of. Once I understand it better I
can say more.

Hi Ondrej,
Thanks for your message and for your original talk. Let me just make a
couple of quick comments and I'll try to be more complete later.
It is not clear to me how the object representing a vector space
should be set up. But something like what you suggest seems right.
For example:

That would be much nicer!

Hi Aaron,
The Set class is important to have as a master class for all kinds of
other classes which should exist, such as Group, Field, Vector space,
Algebra, etc. As it is in Category theory.
A Python set may indeed be a good place to start, but as you suggest,
it would only be a finite set of

It is because it isn't implemented. You can look in sympy/comcrete/
summations.py at eval_sum_symbolic() to see what is implemented. If
you want to implement it, feel free to send in a patch. Either way,
you should create an issue for it, if there isn't one already.
By the way, Sum with a
