latex jupyter notebook it does not work

Question

I started using python with the jupyter notebook and the problem is that the printing is not like the standard LaTeX My cell:

%%latex
\begin{center}
$(a+b)^{2} = a^{2}+2ab+b^{2}$
\end{center}

The result in the notebook looks like in the following picture:

Answer 1

from jupyter docs:

The subset of latex which is supported depends on the implementation in the client. In the Jupyter Notebook, this magic only renders the subset of latex defined by MathJax here.

You could use markdown to display your formula: use single $ to indicate latex, or double $$ to center it. You need to format your cell as markdown instead of code

Your cell becomes one of these two lines:

$$(a+b)^{2} = a^{2}+2ab+b^{2}$$
$(a+b)^{2} = a^{2}+2ab+b^{2}$

You must run the cell to display markdown.

Answer 2

I had a similar problem. A certain set of latex equations in my ipython notebook just stopped rendering properly. It turned out that my latex interpreter had gotten into a weird state because I executed a cell with the code \def in it, by accident.

To fix the problem, I just saved my notebook, stopped the python kernel, closed the notebook in the browser, then re-opened it again and re-executed all the cells. This fixed the problem, and the equations rendered correctly again.
