# Youngwhan's Simple Latex

#### How to use

- Usage: [math]{Latex Syntax}[/math]
- For example, [math]x^2+y^2[/math].

#### Option1: pre

- Usage: [math pre={Choose Number}]{Latex Syntax}[/math]
- [math pre="0"]{Latex Syntax}[/math]: Displays latex expression. It's equivalent to [math]{Latex Syntax}[/math]
- [math pre="1"]{Latex Syntax}[/math]: Wrapping with <pre>, which shows [math]{Latex Syntax}[/math] itself. This just help to show the code itself
- [math pre="2"]{Latex Syntax}[/math]: Same as pre="1", but it doesn't show [math] and [/math] code.

#### Option2: align

- Usage: [math align="{Choose Alignment}"]{Latex Syntax}[/math]
- {Choose Alignment}: "top" (default), "bottom", "middle", "left", "right".
- It is equivalent to <img style="float:{Choose Alignment}"/>
- For example, [math align="left"]x^2+y^2[/math] will put the latex form at left with the wrapping text.

Then, put "http://yourdomain.com/cgi-bin/your-own-mathtex.cgi" in the YW Latex Settings.

#### What is difference mathtex.cgi and mimetex.cgi

- Based on mimeTex, mathTeX is the successor to mimeTeX. It's based on real LaTeX and renders higher quality images than mimeTeX.
- So, mathtex gives better quality of image.

#### Error: your-domain is not authorized to use mathTeX on this server

- This is due to the security issue. Based on John Forkosh, it is because your page doesn't deliver "HTTP_REFERER".
- Solution is to put this into your header.php in your theme ( {YOUR-WORDPRESS-DIRECTORY}/wp-content/themes/{THEME-NAME}/header.php )

<meta name="referrer" content="always">

- Alternatively, you may use without worring about the error
