How to write LaTeX in IPython Notebook?
任何人都可以分享方式，如何在IPython Notebook中编写LaTeX代码？
This came up in a search I was just doing, found a better solution with some more searching, IPython notebooks now have a %%latex magic that makes the whole cell Latex without the $$ wrapper for each line.
Refer notebook tour for Rich Display System
IPython notebook uses MathJax to render LaTeX inside html/markdown. Just put your LaTeX math inside $$ .
$$c = sqrt{a^2 + b^2}$$
Or you can display LaTeX / Math output from Python, as seen towards the end of the notebook tour:
from IPython.display import display, Math, Latex
display(Math(r'F(k) = int_{-infty}^{infty} f(x) e^{2pi i k} dx'))
Use $$ if you want your math to appear in a single line, eg,
$$a = b + c$$ (line break after the equation)
If you don't need a line break after the math, use single dollar sign $, eg,
$a = b + c$ (no line break after the equation)
