Mathematical Typesetting - Assignments ------------------------------------------------------------------------------------------------------------------------

1. Assignment on Spaces 
We left a space between α and a in the tutorial. Now leave different lengths of space using: 
           1.1 \enskip 
           1.2 \quad 
           1.3 \qquad 
        How do these spaces compare with one we created in the tutorial? 
Between α and a, now leave a smaller space with the command \,(i.e., slash comma)

2. Assignment on Fractions using braces  
We want you to create . What happens if you give this command 
 \frac ab cd without braces? Explain. 
What does the following command result in: \frac{ab+1}{cd-1} 
Create this fraction: 
If you use \dfrac in the place of \frac, what happens? For \dfrac to work, you need to use the package amsmath 

3. Assignment on Subscripts and Superscripts  
We want you to create xab. Will the following command work? x_ab. 
            Explain. 
Reproduce this command:  \int_{-\infty}^{\pi/2}xdx 
   1.  What do the commands \int and \pi do? 
   2.   Does it make sense to use \frac in the above? 

4. Assignment on Matrices  
We have used the following commands to build matrices: \matrix, \bmatrix 
Try instead the following matrix commands: \pmatrix, \vmatrix, \Vmatrix 
Remember to use the package amsmath

5. Assignment on Various symbols
Try the symbols on page 12 and 13 of the file chap11-prn.pdf that has been given in the Code files. 

6. Assignment on Package amssymb  
Use the package amssymb 
Try the commands on pages 14 to 16 of the file chap11-prn.pdf that has been given in the Code files. 

7. Assignment on More of TUG India Document  
Reproduce as many commands as possible from chap11-prn.pdf 
This file has been provided in the Code files.
You may copy-paste, directly, from pdf. 
If a command does not work, see if a package has to be used. 

8. Assignment on Paragraph Indent  
We used a command that removes paragraph indents 
Delete this command and repeat this tutorial
