* Objectives
  At the end of this tutorial, you will be able to,
  - Define a list of numbers.
  - Perform elementwise squaring of the list. 
  - Plot data points.
  - Plot errorbars.
  
* Simple Pendulum Data

* Summary 
  In this tutorial, we have learnt to –
  - Declare a sequence of numbers using the function ``array``.
  - Perform elemtwise squaring using the ``square`` function.
  - Use the various options available for plotting like dots,lines.
  - Plot experimental data such that we can also represent error by using the
    ``errorbar()`` function.
* Evaluation
  1. Square the following sequence. 
     - distance\_values=[2.1,4.6,8.72,9.03]

  2. Plot L v/s T in red plusses.
* Solutions
  1. square(distance\_values)

  2. plot(L,T,'r+')
