[IPython-dev] SymPy printing in the ipython notebook

[Jason Moore]

Hi Richard,

I don't think SymPy has tested with IPython 2.0 yet. It is possible that
the printing is no broken... It should display in mathjax/latex by default
in the notebook and pretty print in the terminal.

If you don't mind please submit an issue on github to the main sympy
repository.
