Different ways to include LaTeX in org documents

How embed LaTeX math in org document in described here.

Be careful when nesting math environments between $ $ or $$ $$! You might get unexpected behaviour when starting a line with \begin inside dollar delimiters!

In such cases it is safe to use \begin{equation} enviroment.

To see the baddness of the examples below they need to be exported to pdf format (When exporting to html there are other issues.)

Example 1

Improper

\begin at the beginning of the line inside =$$ $$= or $ $ .
```
$$A =
\left[
\begin{array}{cc}
a & v \\
c & d
\end{array}
\right]$$
```
\[A = \left[ \begin{array}{cc} a & v \\ c & d \end{array} \right]\]
Proper
```
$$A =
\left[\begin{array}{cc}
a & v \\
c & d
\end{array}
\right]$$
```
\[A = \left[\begin{array}{cc} a & v \\ c & d \end{array} \right]\]

Example 2

Improper

Whitespaces after begginning dollar sign or before ending dollar sign (space, tab or newline)
```
$
A =
\left[
\begin{array}{cc}
a & v \\
c & d
\end{array}
\right] $
```
$ A = \left[\begin{array}{cc} a & v
c & d \end{array} \right] $
Proper

Do note that in this example $begin{array} at the beginning of the line is ok!
```
$A =
\left[
\begin{array}{cc}
a & v \\
c & d
\end{array}
\right]$
```
$A = \left[\begin{array}{cc} a & v
c & d \end{array} \right]$

Example 3

Improper

\begin at the beginning of the line inside =$$ $$= or $ $ .
```
$$A =
\left[
\begin{array}{cc}
a & v \\
c & d
\end{array}
\right]$$
```
\[A = \left[ \begin{array}{cc} a & v \\ c & d \end{array} \right]\]
Proper

When using equation environement you can start nested environemnts from the beginning of the line.
```
\begin{equation}
A =
\left[
\begin{array}{cc}
a & v \\
c & d
\end{array}
\right]
\end{equation}
```
\begin{equation} A = \left[ \begin{array}{cc} a & v
c & d \end{array} \right] \end{equation}

Hard space, non-breaking space in org-mode

A way to include non-breaking space (nbsp) in org document to have it properly exported to latex document is presented here https://emacs.stackexchange.com/questions/45083/non-breaking-space-in-org-mode or https://stackoverflow.com/questions/9311538/how-to-make-non-breaking-spaces-ties-in-org-mode-that-exports-properly-to-late
