This document discusses LaTeX and its advantages for researchers. It introduces LaTeX, noting it is indispensable for some disciplines and easier to use than word processors. Some key advantages are its professional typesetting, ability to handle mathematical symbols, platform independence, and free cost. Sections, cross-referencing, tables, graphics, and bibliographies can all be easily created in LaTeX. The document provides examples of basic LaTeX code for these elements. It concludes with resources for learning more about LaTeX such as guides and tutorials.

3. Introduction
• For people in some disciplines, LATEX is virtually
indispensable.
• But if you give it a try, you may wonder how you got
along without it.
• You'll probably have some problems at rest, but it's not
really that hard; simple things can be done very quickly,
and there are lots of resources to help.
• Once you are used to it, LATEX is easier to use than word
processors; in particular, it makes certain parts of writing
scholarly articles much easier.

4. Introduction
• Most of these articles include bibliographies and LATEX has tools to
manage bibliographies.
• Different publishers require different formats, LATEX has tools to
manage these, and some publishers may even provide their own
LATEX formatting templates, so that everything is set up
automatically.
• Papers may include figures and tables, and, when they do, they will
require cross-referencing, and, yes, LATEX has tools to handle this
as well.
• Many papers require revisions, both before and after they are
submitted. LATEX will renumber everything automatically,
references, cross-references, section numbers and everything.
• If you decide to write a book, LATEX can handle books of any
length, and can produce books of real beauty

5. Introduction
• LaTeX pronounced as “tech”
• LaTeX is typeset like
• LATEX is not a word processor.
• It's a document preparation system.
– You write and TeX will place it on the page

6. Advantages of LaTeX
• Professional typesetting
– Best output
• It is the standard for scientific documents
• Processing Mathematical (& other) symbols
• Meaning based structuring (rather than
appearance)
• Knowledgeable and helpful user group
• Its FREE!
• Platform independent

7. Disadvantages of using LaTeX
• Feels Hard to write disorganized documents.
• You can’t see the output while you type.
• Customizing is tedious.

8. Why using LaTeX
1. Sectioning:
If we are writing a long article. It has sections.
LATEX will handle the numbering, the formatting, the
spacing, and all that, leaving you free to do the writing
and the thinking. And LATEX won't try to guess what
you're thinking, or start numbering sections whenever
you type a number, or start indenting.
Example:
section{Section Title}
subsection{Title}
subsubsection{Title}

9. 2. Cross-Referencing
At some points in your article you want to refer to other
parts, or to figures, or tables. No problem. At the part
you want to refer to you need a label command, and at
the point where you make your reference, you need a
corresponding ref command.
Example:
In subsection ref{SS:section} I showed you how to create
sections and subsections.
This produces the following:
In subsection 3.1 I showed you how to create sections
and subsections.

10. 3. Tables can be created
Example:
begin{table}
centering
begin{tabular}{lrr}
Quantile & Male & Femalehline
0% & 59 & 44
50% & 69 & 64
100% & 77 & 71
end{tabular}
caption{Quantiles of male and female heights}
label{tab:malefemale}
end{table}
Table appears to be
Quantile Male Female
0% 59 44
50% 69 64
100% 77 71

11. Some Tables

12. 4. Graphics
For social scientists, perhaps the most useful are ways to
directly import .pdf and .eps files that are created by
other programs, such as statistical packages.
Example:
begin{figure}
centering
includegraphics{diagram1}
caption{This is an example of a figure.}
label{fig:example}
end{figure}

13. Some Figures & Graphs

14. 5. Equations
TeX system is to create something that allows simple
construction of mathematical formulae, and looks
professional when printed. This is hoe it is useful for
every scientific community.
Example:
begin{equation}
x = a_0 + cfrac{1}{a_1 + cfrac{1}{a_2 + cfrac{1}{a_3 +
cfrac{1}{a_4} } } }
end{equation}

15. 6. Biblography
For any academic/research writing, incorporating
references into a document is an important task.
Fortunately, LaTeX has a variety of features that make
dealing with references much simpler, including built-in
support for citing references.

16. A Simple LaTeX Document
documentclass{article}
begin{document}
This is some sample text.
end{document}

17. Parts of a LaTeX Document: documentclass
• First line of all LaTeX documents
• Specifies the type of the document
• The documentclass dictates the fontsize of
headings, spacing between paragraphs and other
formatting.
documentclass
{article}
{report}
{book}
{letter}
Basic Classes

18. Parts of a LaTeX Document: Environment
Start with begin{. . .}
End with end{. . .}
begin{document}
begin{equation}
…
end{equation}
end{document}

19. Where to find LaTeX
• There is a huge variety of materials to help you
learn more about LATEX:
CTAN (The Comprehensive TEX Archive Network) is
a repository of TEX macros, packages, formats,
utilities, and other goodies, and has lots of
material, some of it for beginners.
Guide to LATEX [2] which is an excellent
introduction to LATEX.
Math into LATEX [1], which is particularly useful if
you have to type a lot of math.

20. 5 Best Practices for a Good Researcher
• Practice Writing : Simple, clear and direct
• Practice Creating your own Documents : Use any word
processor
• Practice Showing : Don’t tell your reader, instead show
what you have done
• Practice Edit, edit, edit: Once you finish a piece of
writing, let it be revised/edited to make it better.
• Practice to understand a classic work : Practicing to
understand what makes a great writing/work is one of
the best ways to grow your own skills
