Equations

Equations in Mediawiki are rendered using the very powerful markup language in LaTex. Standardizing on LaTex provides for a uniformly supported protocol by many software platforms. This facilitates the collaboration between multiple authors of the same page by eliminating translation errors and providing consistent procedures with minimal impact on markup software choices between authors.

Many modern equation editors, including MS Word, will convert equations to LaTex, and this conversion can be copied/pasted into the wiki page using the source editor (Edit source tab upper right). Here is a link to a video showing how to convert equations in MS Word to LaTex.

Alternatively, authors can create LaTeX equation markup in the free LaTex editor LyX. The equation markup can then be copied/pasted into a wiki page using the source editor (Edit source tab upper right).

For LibreOffice users there are LaTex "addons". Search for "LibreOffice LaTex addons" for options.

The visual editor ("Edit" tab upper right) has a relatively simple equation editor that can be accessed by Insert->More->Math Formula. However, more complex equations such as those involving matrix algebra will be more successfully marked up using tools such as MS Word or LyX, and copied/pasted.

<Math></math> tags

The equation markup in LaTex must appear in between the <Math> and </math> tags in the Wikitext markup source accessed by the Edit source tab in the upper right of the page. For example,

$R_{W}={\frac {W_{t}-W_{B}}{A_{t}}}\times 200+W_{B}$

was rendered with,

<math>
R_W = \frac{W_t - W_B}{A_t}\times 200 + W_B
</math>

Inline math

Equations can be rendered in a line of text simply by beginning the part of the sentence with the equation with <math> and ending the equation part with </math>. For example,

Let $A_{t}$ be the age at weighing in days; let $W_{t}$ be the weight in kilograms; let $W_{B}$ be the recorded birth weight or a breed standard,

was rendered by adding the following to the page in the Edit source editor,

Let <math>A_t</math> be the age at weighing in days; let <math>W_t</math> be the weight in kilograms; <math>W_B</math> be the recorded birth weight or a breed standard,

This type of simple inline math can be easily input using the Insert->More->Math formula in the visual editor (Edit in the upper right of the page).

Labeling equations

Equations should be numbered and labeled in italics. A stand-alone description of the equation should be given.

Equation 1. Age-adjusted weaning weight.

$R_{W}={\frac {W_{t}-W_{B}}{A_{t}}}\times 200+W_{B}$

Equation references

A reference must be given for the sources of any equations using the <ref></ref> tag.
