While browsing [this page](https://docs.sympy.org/1.5.1/tutorial/matrices.html#basic-operations) in the docs, I saw that trying to assign a `Matrix` object to `N` fails.

Whenever you evaluate something it says `Error: .`. Here is an example traceback from the logs ```pytb (/base/alloc/tmpfs/dynamic_runtimes/python27g/7cb976f64e72c78c/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py:291) Traceback (most recent call last): File "/base/alloc/tmpfs/dynamic_runtimes/python27g/7cb976f64e72c78c/python27/python27_lib/versions/1/google/appengine/runtime/wsgi.py", line 273, in Handle result...

`plot()` doesn't seem to work. Would be nice if it did. 
It'd be nice if I was on the SymPy 0.7.6 doc version, for example, that when I press "run in sympy live" on various code cells that the sympy live...

Hi folks, there is something strange with plot of factor(x**4/2 + 5*x**3/12 - x**2/3). Compare it with Wolfram Alpha. Regards, Simone
