Dear All,
In my work related to the Diophantine Module for SymPy (PR
#2168https://github.com/sympy/sympy/pull/2168)
I came across a situation where I want to find the degree of an expression.
I initially used max(degree_list(expr)) but it doesn't always return what I
want.

Yes, use the @slow decorator. Then run the tests with --slow. Be
sure to also include the --timeout flag, as some of the slow tests run
for a **really** long time. We also need to run these tests with

The following code produces the exception:

I will write a more complete answer soon, but in the meantime you can
check the `examples` folder. In the docs for the plotting module

Hi Stefan,
This is awesome, thanks a lot! I tested your notebook, it works great.
As far as the

I guess it was assumed it would do this
I suppose this could be called a feature since the routine will fail if you
comment out the error since it needs a sign change to find the root. But
perhaps the refine_root could check return the evaluated root in that range

Perhaps it would be better to evaluate
Indeed, the example notebooks assume that certain setup was performed.
I guess it is a leftover from before I learned that it is an ipython
antipattern.

Yeah, just yesterday I realized that it's probably better to launch
then notebook just with

and then just have a cell that initializes things properly (if
needed), so for plotting I use:

Regarding the radius of convergence, apparently the root test is a
perfect test. See
http://en.wikipedia.org/wiki/Cauchy%E2%80%93Hadamard_theorem and
http://en.wikipedia.org/wiki/Radius_of_convergence#Theoretical_radius.
I did not know this fact. This is nice, because SymPy is good at
