4.1 Working with maths and Tex
We can write "normal" latex equation by using the math class. For instance the following code
<math> {\textbf x}_{t} = {\textbf f}({x}_{t1},{u}_{t1},{p}_{t1}) </math>
is displayed as
In order to use tex commands from the amsmath package we use the class amsmath. Automated numbering of equations works within a single amsmath environment. The class amsmath uses the tex template defined in /var/www/html/mediawiki/extensions/wikitex/wikitex.math.inc.tex
I changed the template such that we can define global commands. The template looks like
\documentclass[10pt]{article} \usepackage{amssymb,amsmath,amscd,concmath} % we can define whatever comments we would like to use for consistency. % of course we have to somewhere list this special commands (may be we can use % a pop up with editiing help or somkething similar % for instance: \newcommand{\rs}{\ensuremath{\gg}} %right shift >> \newcommand{\ls}{\ensuremath{\ll}} %left shift << \newcommand{\rr}{\ensuremath{\ggg}} %right rotate >>> \newcommand{\lr}{\ensuremath{\lll}} %left rotate <<< \pagestyle{empty} \begin{document} %value% \end{document}
For instance:
code fragment  displayed equation 

<amsmath> \begin{equation} a = \sum_{i=0}^{n}{2^i} \end{equation} </amsmath> 

%value% in textemplate is \begin{equation}...\end{equation} 
If we start a new amsmath environment then the equation numbering starts from counter=1 again. Start a new amsmath environment:
as we see both envrionments start with 1.
Note: so far I have no idea how to refer to an equation
