* Objectives
 At the end of this tutorial, you will be able to,

 - Use ``@interact`` feature of SAGE for better demonstration.
 - Share, publish and edit SAGE worksheets for collaborative learning.
* Pre-requisite
  Spoken tuorial on -
  - Getting started with Sage.
  - Getting started with Symbolics.
* Exercise 1
- Plot the sine curve and vary its frequency using the ``@interact`` feature.
* Exercise 2
- Take a string as input from user and circular shift it to the left and
  vary the shift length using a slider.
* Summary
  In this tutorial,we have learnt to,

 - Use interactive features of SAGE using ``@interact``.
 - Publish our work.
 - Edit a copy of one of the published worksheets.
 - Share the worksheets with fellow users.
* Evaluation
 1. Which default argument, when used with ``@interact`` gives a slider 
    starting at 0 and ending in 10.

    - (0..11)
    - range(0, 11)
    - [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
    - (0..10)

 2. What is the input widget resulted by using ``n = [2, 4, 5, 9]`` in the
    default arguments along with ``@interact``.

    - input field
    - set of buttons
    - slider
    - None
* Solutions
 1. (0..10)

 2. Set of buttons
