+  + 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.
