Formulas on a wiki like Ifigenia can be represented in three ways, depending on the formula complexity and tools used:
* Unicode characters - for simple formulas, of course :-)
* Images - for formulas of any complexity, created as an image file (preferably <code>.png</code> or <code>.gif</code>) and [[Help:Upload|uploaded locally]].
* TeX code - for formulas of any complexity - from very simple to extremely sophisticated

Maybe, for the users of Ifigenia TeX-coded formulas may turn out to be the most natural ones. They allow relatively good integration with other TeX documents and they can be further saved as <code>.gif</code> images, for the sake of integration with Word documents.

== Formulas in TeX ==
In the wiki websites, TeX-formulas are distinguished from the rest of the text by enclosing them with the tags <code><math> </math></code>. A handy way is to click the Math button [[Image:Button_math.png]] and then write between the tags.

== Alternatives ==
=== Formulas in simple text ===
These can be produced with:
* the keyboard symbols,
* the symbols from the virtual keyboard (available by clicking on the [[Image:Button_more.png]] button in [[Help:Edit mode|edit mode]])
* any other Unicode symbols
* formatting commands like <code> </code> (subscript), <code> </code> (superscript), <code><nowiki>'' ''</nowiki></code> (italic)

The major drawback is that in this way only one-line simple formulas can be produced; multiline formula, fractions, matrices, etc cannot be created using simple text. However, it can prove handy for really small formula or variables/constants/functions definitions, and for people who do not master TeX.

; Examples
{| width="100%" class="wikitable"
! width="70%" | Source code (in edit mode)
! width="30%" | Result (in read mode)
|-
| <pre>
x2 + y2 = z2
</pre>
|| x2 + y2 = z2
|-
| <pre>
''πA(x) = 1 - (μA(x) + νA(x))''
</pre>
|| ''πA(x) = 1 - (μA(x) + νA(x))''
|-
| <pre>
A = ∑i=1n ai
</pre>
|| A = ∑i=1n ai
|}

=== Formulas in uploaded images ===
: ''You may first want to read [[Help:Upload]] and [[Help:Images and files]].''

The major drawbacks of this approach are:
* Images are difficult to edit, and need external graphic editor for this sake.
* Images may scale down, but may not scale up well (unless in vector graphic format).
* Images files may be unnecessary large.
* Files can only be uploaded by registered users.
