* Objectives
  At the end of this tutorial, you will be able to, 
 - Modify the attributes of the plot -- color, line style,linewidth.
 - Add a title to the plot with embedded LaTeX.
 - Label x and y axes. 
 - Add annotations to the plot. 
 - Set and Get the limits of axes.
* Pre-requisite
  - Spoken tutorial on "Using plot interactively"
* Exercise 1
  Plot sin(x) in blue colour alongwith linewidth as 3
* Exercise 2
  Plot the sine curve with green filled circles.
* Exercise 3
  Plot the curve of x vs tan(x) in red dashed line and linewidth 3
* Exercise 4
  Change the title of the figure such that the whole title is
  formatted in LaTex style
* Exercise 5
  Set the x and y labels as "x" and "f(x)" in LaTex style.
* Exercise 6
  Make an annotation called "root" at the point (-4, 0). What happens
  to the first annotation?
* Exercise 7
  Set the limits of axes such that the area of interest is the
  rectangle (-1, -15) and (3, 0)
* Summary
  In this tutorial,we have learnt to-
  + Modify the attributes of plot by passing additional arguments.
  + Add title to a plot using 'title' command.
  + Incorporate LaTeX style formatting by adding a $ sign before and after the part of the string. 
  + Label x and y axes using 'xlabel()' and 'ylabel()' commands.
  + Add annotations to a plot using annotate() command.
  + Set the limits of axes using 'xlim()' and 'ylim()' commands.
* Evaluation
  1. Draw a plot of cosine graph between -2pi to 2pi with line thickness 4.

  2. Read thorugh the documentation and find out is there a way to modify the
     alignment of text in the command ``ylabel``.
     - Yes
     - No

  3. How do you set the title as x^2-5x+6 in LaTex style formatting.
* Solutions
  1. x = linspace(-2*pi, 2*pi)
     plot(x, cos(x), linewidth=4)
  
  2. No

  3. title("$x^2-5x+6$")
