+* Outline
+  + Modifying the color, line style & linewidth of a plot
+  + Adding a title to the plot (with embedded LaTeX)
+  + Labelling the axes
+  + Annotating the plot
+  + Setting the limits of axes. 
+* Question 1
+  Plot sin(x) in blue colour and with linewidth as 3
+* Solution 1
+  #+begin_src python
+    In []: clf()
+    In []: plot(x, sin(x), 'b', linewidth=3)
+  #+end_src
+* Question 2
+  Plot the sine curve with green filled circles.
+* Solution 2
+  #+begin_src python
+    In []: clf()
+    In []: plot(x, cos(x), 'go')
+  #+end_src
+* Question 3
+  Plot the curve of x vs tan(x) in red dashed line and linewidth 3
+* Solution 3
+  #+begin_src python
+    In []: clf()
+    In []: plot(x, cos(x), 'r--')
+  #+end_src
+* Question 4
+  Change the title of the figure such that the whole title is
+  formatted in LaTex style
+* Solution 4 
+  #+begin_src python
+    In []: title("$Parabolic function -x^2+4x-5$")
+  #+end_src
+* Question 5
+  Set the x and y labels as "x" and "f(x)" in LaTex style.
+* Solution 5
+  #+begin_src python
+    In []: xlabel("$x$")
+    In []: yalbel("$f(x)$")
+  #+end_src
+* Question 6
+  Make an annotation called "root" at the point (-4, 0). What happens
+  to the first annotation?
+* Solution 6
+  #+begin_src python
+    In []: annotate("root", xy=(-4,0))  
+  #+end_src
+* Question 7
+  Set the limits of axes such that the area of interest is the
+  rectangle (-1, -15) and (3, 0)
+* Solution 7
+  #+begin_src python
+    In []: xlim(-1, 3)
+    In []: ylim(-15, 0)
+  #+end_src
+* Summary
+  + Modifying the attributes of plot by passing additional arguments
+  + How to add title
+  + How to incorporate LaTeX style formatting
+  + How to label x and y axes
+  + How to add annotations
+  + How to set the limits of axes
+
+* Thank you!
