There are several evalf problems that were fixed with edits I made in
https://github.com/sympy/sympy/pull/1028 . But it would be great to
have anyone that understands how mpmath/evalf works to do some more
review of it. Mateusz has already said he won't have time for sympy
for a while and I haven't

Yes, this seems inconsistent. Mod sh
To enable MathJax printing in the notebook do:

ipython notebook --profile sympy
OR
* Load the sympyprinting extension in a notebook:
%load_ext sympyprinting

Add and Mul are AssocOp for obvious reasons. Pow is just an expression

I have done it. Especially interesting will be to have an "asymptote

Hi,
Thanks for the feedback. I will try to prepare some kind of a

discuss them.

Hi.
Some of these things are SymPy bugs, and some are IPython bugs. If
--profile=sympy doesn't work, and you are in fact using the newest
version of SymPy/IPython, it should work. If not, it is an IPython
bug, and should be reported to them.
As far as adding a GUI to the notebook to enable this,
Hi.
This is great. I think we definitely need to improve that module.
You've already completed the patch requirement, so I would spend time
discussing your idea with the community. Once you've got a solid
idea, you can start writing an application (though it's still early,

The framework with matplotlib and Pyglet backends is right now beeing
reviewed for inclusion in master. See https://github.com/sympy/sympy/pull/673.
This doesn't mean you couldn't imporove it even further though.

If you search the list you will find that there have been long but

Getting physics to utilize the tensor module sounds like a great idea. If

As someone who has followed and used many of your "minor" contributions

Because that's what I was playing with at the time, so no real reason.
Is it faster?
Nope

Is there a good reason to use numpy.random.random instead of just

Do you care about the distribution of these numbers? There are many
ways to generate random rational numbers, and they will be distributed
differently. For example, you could do
(random_integer)/(random_integer) (with the integers coming from some
distributions).
If you want an even distribution
