Hello friends. Welcome to this spoken tutorial on Getting started with

sage and sage notebook.

{{{ Show the slide containing the title }}}

{{{ Show the slide containing the outline }}}

In this tutorial, we will learn what Sage is, what is Sage notebook,

how to start and use the sage notebook. In the notebook we will be

specifically learning how to execute our code, how to write

annotations and other content, typesetting the content and how to use

the offline help available.

{{{ Show the slide on what is Sage }}}

To start with, What is Sage? Sage is a free, open-source mathematical

software. Sage can do a lot of math stuff for you including but not

limited to algebra, calculus, geometry, cryptography, graph theory

among other things. It can also be used as aid in teaching and

research in any of the areas that Sage supports. So let us start Sage

now

{{{ Shift to terminal }}}

We are assuming that you have Sage installed on your computer now. If

not please visit the page

http://sagemath.org/doc/tutorial/introduction.html#installation for

the tutorial on how to install Sage. Let us move on now.

On the terminal type::

  sage

This should start a new Sage shell with the prompt sage: which looks

like this

{{{ Show what is displayed on the terminal }}}

So now we can type all the commands that Sage supports here. But Sage

comes bundled with a much much much more elegant tool called Sage

Notebook? What is Sage Notebook? Sage Notebook provides a web based

user interface to use Sage. So once we have a Sage notebook server up

and running all we want is a browser to access the Sage

functionality. For example there is an official instance of Sage

Notebook server running at http://sagenb.org You can visit that page,

create an account there and start using Sage! So all you need is just

a browser, a modern browser 

{{{ Intentional *cough* *cough* }}}

to use Sage and nothing else!

However we can also run our own instances of Sage notebook servers on

all the computers we have a local installation of Sage. To start the

notebook server just type::

  notebook()

on the Sage prompt. This will start the Sage Notebook server.

If we are starting the notebook server for the first time, we are

prompted to enter the password for the admin. Type the password and

make a note of it. After this Sage automatically starts a browser page

for you with the notebook opened.

If it doesn't automatically start a browser page check if the Notebook

server started and there were no problems. If so open your browser and

in the address bar type the URL shown in the instructions upon running

the notebook command on the sage prompt.

{{{ The notebook() command gives an instruction telling 

Open your web browser to http://localhost:8000. Point towards it }}}

In our case it is http://localhost:{{{ Tell whatever is shown }}}

{{{ Show the browser with Sage notebook }}}

If you are not logged in yet, it shows the Notebook home page and

textboxes to type the username and the password. You can use the

username 'admin' and the password you gave while starting the notebook

server for the first time. There are also links to recover forgotten

password and to create new accounts.

{{{ If you are logged in tell that you are logged in, log out and show

what is said above for the login page }}}

Once we are logged in with the admin account we can see the notebook

admin page. A notebook can contain a collection of Sage Notebook

worksheets. Worksheets are basically the working area. This is where

we enter all the Sage commands on the notebook.

The admin page lists all the worksheets created. On the topmost part

of this page we have the links to various pages. The home link takes

to the admin home page. The published link takes us the page which

lists all the published worksheets.

This brings us to the end of the session on using Sage notebook. In

this tutorial session we learnt
