## Markdown In Jupyter Notebook

Posted on by

Jupyter Book uses MathJax for typesetting math in your HTML book build.This allows you to have LaTeX-style mathematics in your online content.This page shows you a few ways to control this.

Markdown in Jupyter Notebook In this tutorial, you'll learn how to use and write with different markup tags using Jupyter Notebook. Markdown is a lightweight and popular Markup language which is a writing standard for data scientists and analysts. In this tutorial, you'll learn how to use and write with different markup tags using Jupyter Notebook.

Tip

By default MathJax version 2 is currently used.If you are using a lot of math, you may want to try using version 3, which claims to improve load speeds by 60 - 80%:

See the Sphinx documentation for details.

To insert in-line math use the $ symbol within a Markdown cell.For example, the text $this_{is}^{inline}$ will produce: (this_{is}^{inline}). ## Math blocks¶ You can also include math blocks for separate equations. This allows you to focus attentionon more complex or longer equations, as well as link to them in your pages. To use a blockequation, wrap the equation in either $\$ or begin statements.

For example,

results in:

[ int_0^infty frac{x^3}{e^x-1},dx = frac{pi^4}{15}]

### Latex-style math¶

You can enable parsing LaTeX-style math blocks with the amsmath MyST extension. Enable it by adding the following to _config.yml

Once enabled, you can define math blocks like so:

which results in:

[begin{gather*}a_1=b_1+c_1a_2=b_2+c_2-d_2+e_2end{gather*}]
(2)¶[begin{align}a_{11}& =b_{11}& a_{12}& =b_{12}a_{21}& =b_{21}& a_{22}& =b_{22}+c_{22}end{align}]

The MyST guides to dollar math syntax, LaTeX math syntax, and how MyST-Parser works with MathJax.

### Numbering equations¶

If you’d like to number equations so that you can refer to them later, use the math directive.It looks like this:

For example, the following code:

will generate

(3)¶[w_{t+1} = (1 + r_{t+1}) s(w_t) + y_{t+1}]

Alternatively you can use the dollar math syntax with a prefixed label:

which generates

(4)¶[ w_{t+1} = (1 + r_{t+1}) s(w_t) + y_{t+1}]

Note

Labels cannot start with an integer, or they won’t be able to be referenced andwill throw a warning message if referenced. For example, :label:1 and :label:1eq cannotbe referenced.

If you have created an equation with a label, you can link to it from within your text(and across pages!).

You can refer to the equation using the label that you’ve provided by usingthe {eq} role. For example:

results in

• A link to an equation directive: (3)

• A link to a dollar math block: (4)

Note

## What Is Markdown In Jupyter Notebook

labels inside LaTeX environment are not currently identified, and so cannot be referenced.We hope to implement this in a future update (see executablebooks/MyST-Parser#202)!
