Devanagari in LaTeX

Step 1: Start the Package Manager and install devanagari package.
Step 2: Create a dn file using notepad

Sample (hindi1.dn)

\documentclass{article}
\usepackage{devanagari}
\begin{document}
{\dn amira khusaru akhatara|}
\end{document}


Step 3: Pre-process the dn file to generate the tex file

Command
devnag hindi1.dn

This command will generate hindi1.tex file shown below

\def\DevnagVersion{2.17}
\documentclass{article}
\usepackage{devanagari}
\begin{document}
{\dn aEmr \7{K}sz aKtr.}
\end{document}

Step 4: Run the tex file

Output

Numerals and Rupee Symbol in LaTeX

For numerals use \dnnum command and for rupee symbol use \rupee command

Sample Code (.dn file)

\documentclass{article}
\usepackage{devanagari}
\usepackage{tfrupee}
\begin{document}
{\dn kiimata}:
 \rupee~{\dn \dnnum 5,500}

Mathematics in LaTeX

Mathematical Expressions
In LaTex we have two modes to use mathematical expressions (inline and display mode)

For inline mode use any one of these delimiters.
1.  \( \)
2.  $ $
3.  \begin{math} \end{math}

Ex.
$c=a+b$

In displayed mode we have two versions (numbered and unnumbered)

We can use  any one of these delimiters in display mode
1. \[ \]
2. $$ $$
3. \begin{displaymath} \end{displaymath}
4. \begin{equation} \end{equation}

Ex.
$$ c=a+b $$

Note: include package amsmath
\usepackage{amsmath}

In Latex we can use the symbols ^  for superscripts and symbols  _ for subscripts.

Ex. 
\documentclass[options]{article}
\usepackage{amsmath}
\begin{document}

$$ x_1^2 + x_2^2 = x_3^2 $$

$$ x^{a \beta} - 1 = y_{ijk} + y_{lm}  $$

$$ ((xa)^n)^{p+q} = xa^{\theta}  $$

\[ \int\limits_0^\infty a^2 + b^2 \ dx \]

$$ \sum_{i=0}^{\infty} \frac{2}{n^s}
= \prod_p ^ n \frac{i}{1 - p^{-s}} $$

\end{document}

Output

Label in equation
We can use label for future reference
\documentclass[options]{article}
\usepackage{amsmath}

\begin{equation} \label{eq01}
e^{\pi i} + 1 = 0
\end{equation}
The is an example of equation in \ref{eq01} Label
\end{document}

OUTPUT

Multiline Equation
use \begin{multline} command for numbered equation and \begin{multline*} for unnumbered equation.

\documentclass[options]{article}
\usepackage{amsmath}

\begin{multline}
f(x) = 4x^6 + 4x^5y + 5x^4y^2 + 9x^3y^3\\

Figures in LaTex

Figures

In LaTex we have figure commands to use a figure.  We can add PDF, PNG, JPEG\or GIF files.

\begin{figure}

......

\end{figure}

Ex. 

\documentclass[options]{article}
\usepackage{graphicx}
\begin{document}
\begin{figure}[h]
\centering
\includegraphics[width=0.5\textwidth]{img.jpg}
\caption{Here is my image}
\label{image-myimage}
\end{figure}
\end{document}

[width=1\textwidth]  specifies the width of the picture 

For alignment from left or right we need to add
\usepackage[export]{adjustbox}

Ex.
\includegraphics[width=0.5\textwidth, right]{img}

Multiple images in one figure

use package{subcaption} and the environment \subfigure 

Ex.

\documentclass[options]{article}

\usepackage{graphicx}

\usepackage[export]{adjustbox}

\usepackage{subcaption}

\begin{document}

\begin{figure}[h]

\begin{subfigure}{0.5\textwidth}

\includegraphics[width=0.9\linewidth, height=5cm]{Table1} 

\caption{Caption1}

\label{fig11}

\end{subfigure}

\begin{subfigure}{0.5\textwidth}

\includegraphics[width=0.9\linewidth, height=5cm]{Table2}

\caption{Caption 2}

\label{fig12}

\end{subfigure}

\caption{Caption for this figure with two images}

\label{fig2}

\end{figure}

\end{document}

Wrapping text around a figure

import package wrapfig shown below

Ex.

\documentclass[options]{article}

\usepackage{graphicx}

\usepackage{wrapfig}

\begin{document}

\begin{wrapfigure}{l}{0.25\textwidth}

\includegraphics[width=0.9\linewidth]{Table1} 

\caption{Caption1}

\label{fig1}

\end{wrapfigure}

\end{document}

Note:

\textwidth is the width of the total text block

\columnwidth is the width of a single column of text

\linewidth means the current size of the line of text

\graphicspath{ {./img/} } if you want to put images in a folder named img under the directory of the tex document


use absolute path if the location is different

\graphicspath{ {c:/user/img/} } this command should be written in preamble


for Linux, Mac OS

\graphicspath{ {/home/user/img/} }


for multiple folders

\graphicspath{ {./img1/}{./img2/} }


for scaling

\includegraphics[scale=2]{img-name}

for definining specific width and the height of the image

\includegraphics[width=3cm, height=4cm]{lion-logo}


For rotation

\includegraphics[scale=1.2, angle=45]{lion-logo}


Positioning parameters 

\begin{figure}[t]

h: Places approximately at the same point it occurs in the source 

t: Places at the top of the page

b: Places at the bottom of the page

p: Put on a special page for floats only.

!: Override internal parameters LaTeX determines best positions

Table in LaTeX

Table

In LaTeX we use tabular command to typeset a table. 

\begin{tabular}{...}
......

\end{tabular}

The codes for columns are defined as follows

l left-alignment

r right-alignment

c centre-alignment

| for vertical line

& is used to separate columns

\\  for end of a row
\newline for a new line within a cell 

\hline for a horizontal line.

\cline{i-j} inserts a partial horizontal line between column i and j

Ex. {ll} (i.e. left left ) is used to create 2 columns with left-alignment text without vertical lines , whereas {|l|r|} (i.e. left right )  for 2 columns. The first column is left aligned and second column is right aligned  with vertical lines.
