1 Hello friends.

     2 

     3 This tutorial is a self-assessment tutorial and you will be able to assess 

     4 yourself on the concepts learnt in the Module "Plotting Expetimental data"

     5 

     6 As with all other assessments we will first start with a few short questions 

     7 that will not take you more that 15 to 20 seconds to answer. Then we shall move

     8 on to a bigger problems that should take you about 5 mins.

     9 

    10 {{{ Always show slide and explain the problem }}} 

    11 

    12  * What is the shape of plot resulting from the following piece of code::

    13 

    14        x = linspace(0, 2*pi, 4)

    15        plot(x, sin(x))

    16 

    17  * #[Nishanth]: Hav to add a simple question on scatter plot

    18 

    19  * #[Nishanth]: Hav to add a simple question on pie chart

    20 

    21  * Input file contains 25 lines of data, each containing 5 values seperated by

    22    spaces. What is the shape of the resulting matrix from the command::

    23 

    24        loadtxt("input-file.txt", unpack=True)

    25 

    26 {{{ Big problem - 5 mins }}} 

    27 

    28 The input file ``pos.txt`` contains two columns of data. The first column 

    29 contains x position and second column contains y position of a particle in

    30 flight. Plot the trajectory of the particle. What kind of motion is it?
