I attempted to follow the examples in
http://nbviewer.ipython.org/github/ipython/ipython/blob/master/examples/notebooks/SymPy%20Examples.ipynb
If I open a new notebook and carry out the steps below the output is
mathematically correct but it isn't displayed in latex/mathjax format:
from IPython.display import display
from sympy.interactive import printing
printing.init_printing()
from __future__ import division
import sympy as sym
from sympy import *
x, y, z = symbols("x y z")
k, m, n = symbols("k m n", integer=True)
f, g, h = map(Function, 'fgh')
Rational(3,2)*pi + exp(I*x) / (x**2 + y)
The output is:
3*pi/2 + exp(I*x)/(x**2 + y)

If I open a terminal in the same directory and repeat these steps the
output is displayed in a pretty printing format:

I imagine I'm missing something simple but I haven't been able to figure
out what it is. Any help would be appreciated.
