# Markdown Language

A great feature of the Jupyter Notebooks is that they can contain formatted text, mathematical formula, and embedded images, via the use of the Markdown language.

Markdown is a rich language: a quick introduction to it is available here: https://guides.github.com/features/mastering-markdown/

Some quick points:

## Editing and typesetting

Within the Jupyter notebook, you simply type your text and Markdown symbols into a cell, and hit “shift-return” to typeset the cell into pretty text (and math). Click on the cell again to undo the typesetting, so you can edit and fix your text. Make sure, of course, that you have marked the cell as “Markdown” and not “Code.”

## Headers

Headers are made by starting the line with one or more hash marks #.

## Emphasis

Add emphasis by surrounding text with asterix or underscores.

`* italics * and ** bold **`

yield * italics* and ** bold **.

### Lists

Type this:

to get a list like this:

Apple

Orange

Pear

Use numbers instead, to get an enumerated list

#### Web links

Type this `[GitHub](http://github.com)`

to get a clickable weblink like this: GitHub

#### Images

#### Mathematics

Use the dollar sign `$`

to indicate the start and end of LaTeX code for your math.

Here is the code for basic integral `$\int \cos(x) dx = \sin(x)$`

which results in this display. $\int \cos(x) dx = \sin(x)$
