Help:LaTeX Editing



In general, contributors are assumed to be up to speed with some form of $\LaTeX$; a web search should be sufficient to find ample reference on how to get started with it, should you still need to.

The "External references" section below may also be consulted.

The $\LaTeX$ interpreter used on this site is brought to you by MathJax.

This produces an experience different from that produced by the MediaWiki interpreter which is (at time of writing) the one used by Wikipedia and other places.

It also has a subtly different syntax in places. Specific instances will be detailed where relevant.

$\LaTeX$ delimiters
To display an equation in line with some text, the equation should be enclosed in single dollar signs:

Note that  also works, but takes more effort to type and so is less recommended.

There may (but we hope not) still be some pages with  in them. This is a holdover from when MediaWiki was the interpreter used for $\LaTeX$ commands. It still works in MathJax after a fashion but on transcluded pages, such enclosed $\LaTeX$ will not be converted to mathematical symbols.

If you see any, then feel free to change them to  signs, as they should not be there.

No longer supported
The following $\LaTeX$ commands are not supported in MathJax, but may still be present in some pages. When found they need to be replaced.


 * For $\lor$:  to be replaced by


 * For $\land$:  to be replaced by


 * For $\R$:  to be replaced by


 * For $\varnothing$:  to be replaced by


 * For $\exists$:  to be replaced by


 * For $\operatorname{sgn}$:  to be replaced by


 * For producing fixed width text in math mode:  needs to be replaced by.

If you find any more examples, add them here.

External references
It may not be exactly the same version of $\LaTeX$, but I always find this page helpful as a first, quick overview:


 * David R. Wilkins, "Getting Started with LaTeX"

This is also a good reference page, pertaining to MediaWiki $\LaTeX$:


 * Displaying a formula in MediaWiki

but be aware that not all commands are supported.

This is a link of all the currently supported commands available:
