Okay so I just talked with Sachin on this. As Gilbert says, we should plan
before we start work.
Initially, my proposal had a distinction between a CoordSys class and a
RefFrame class. We are at a similar point now. Nevertheless, the two ways
we thought this could work was by:
a) Subclassing t

Alright then. We will go with option (a). @Gilbert and @Sachin, can you
come on the IRC tonight?

Hello. Has anyone tried to use the SymPyPrt IPython extension for
pretty pretting in *ubuntu Raring?
After upgrading to Raring, I find that I can no longer use the
extension in either IPy2 or IPy3. Previously on Precise it worked out
of the box for IPy2 and after some effort for IPy3. Now I get th

Hello,
I have finished work on two heuristics and the 3rd one seems a bit vague

Can you try it in the git master (you don't have to install it, just
git clone and run the IPython notebook from that directory)? See

is_algebraic in the new assumptions means algebraic over the
rationals. Your definition of algebraic means algebraic over a
rational function field over the rationals. In other words,
Q.algebraic(a) means a satisfies a polynomial over QQ (the rational
numbers), a.is_algebraic_function() means that
I, Gilbert and Sachin met up today on the IRC. We talked about how exactly
will we implement the Reference Frames - that is - how the data regarding
position and orientation will be stored. Here's the conclusion we reached:
1. The vector module will have a RefFrame class that supports positionin

OK, new design question. At http://docs.sympy.org/tutorial/, I've
changed the text alignment from justified to left. How does this look
to people (I can push up a comparison if it would help)? The justified

how I feel about the
I feel that text that is more left justified and has font size around
14 px would be easier to read on screen. What do you feel about it. I
don't know if it acceptable in a python-type doc.

In the git SymPy, it uses latex to render in the qtconsole. So that
segfault is likely coming from there. Otherwise, it uses matplotlib,
so you need to have that installed.

If I have code like so:
x = sympy.Symbol('x')
y = 1 / (x + 1)**2
it evaluates to
y = (x + 1)**(-2)
is there a way to prevent that happening and have it remain as 1 / (x +
1)**2.
OR: alternatively, is there a way to retrieve 1 / (x + 1)**2 from the
canonical form? I've looked at the doc

Internally, there is no difference between 1/(x + 1)**2 and (x +
1)**-2. There is no class in SymPy that represents division. 1/x is
represented internally as just Pow(x, -1).
If all you care about is printing, then I recommend you modify the printer.
Which printer are you using? What you need

Hmm -- it seems it's a DVIPNG bug for whatever reason. Even (the dvi
output of) a simple LaTeX document like:
\documentclass[16pt]{article}

Is there a mechanism in place to allow very slow tests to run? We have one
very robust test problem for the mechanics package that runs the
KanesMethod object through the ringer. We'd like to include the test but it
takes 3 minutes on a decent machine to run.

Automating the release sounds like a great sprint topic, one that is very
tractable and will provide a long needed feature.

Ok cool I thought it might be a case of just having to modify how I print.
I'm not using any special printer - just doing print sympy.latex(y)
Thanks for your quick response!!! :- )
