# Here's a short script that shows how LaTeX formulas can be output and 
# printed in the IPython console.  It uses the IPython.display module.  This
# is the one way that I've found that works for me.  
from IPython.display import display, Math, Latex
display(Math(r'F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx'))
display(Math(r'\frac{\partial f}{\partial x} = \frac{\partial}{\partial x}\left[b(x) + c(x)\right]'))

$\displaystyle F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx$

$\displaystyle \frac{\partial f}{\partial x} = \frac{\partial}{\partial x}\left[b(x) + c(x)\right]$
