Template:Math/doc

The math template formats HTML&mdash;or wikimarkup generated&mdash;mathematical formulas in the similar fashion as MathJax, a web-based TeX formula interpreter implemented as a cross-browser JavaScript library. The template has the advantage of not requiring Javascript to be enabled on the user's browser, and also of having less of the flash of unstyled content issue than MathJax. The template uses the  class by default for inline text style formulas, which aims to match the size of the serif font with the surrounding sans-serif font (see below), or the   class for stand-alone display style formulas if either of the   or   parameters are used (using the bigmath template gives you a default size of 165% for stand-alone display style formulas). The template also prevents line-wrapping.

Usage
Use this template for inline, non-complex formulas as an alternative to using the  format (see: Help:Math).

Examples
$f(x) = b^{x} = y$
 * produces: $f(x) = b^{x} = y$

$sin &amp;pi; = 0$
 * produces: $sin &pi; = 0$.

$∫ +&amp;infin; 0 e^{−x} dx = 1$
 * produces: $∫ +&infin; 0 e^{−x} dx = 1$

$1⁄2 − 1⁄3 = 1⁄6$
 * produces: $1⁄2 − 1⁄3 = 1⁄6$. Note the triple-apostrophes have set the whole formula as bold.

$(√2)^{2} = 2$
 * produces: $(√2)^{2} = 2$.

Use of equals-sign and absolute value bars
The equals sign, =, and bar, |, are used as syntax by the wiki template system. Therefore, if a single equals-sign ("=") is used, it will fail to render, instead showing " ". For example, the following template-coding would be invalid:

$1 + 2 = 3$
 * produces: $1 + 2 = 3$, which is invalid code

To resolve this, either: (a) Start the formula with " " as in: $1 + 2 = 3$
 * produces: $1 + 2 = 3$, or else, (b) include the equals-sign in double-braces "=" as in:

$1 + 2 = 3$
 * produces: $1 + 2 = 3$.

A similar difficulty concerns the vertical bars ("|") used to indicate absolute value, which without care would get interpreted as part of the template syntax. The solution is different than for the equals sign: such bars should be entered as " | ": $|f(x) − a| < ε$
 * produces: $|f(x) − a| < ε$.

This example can also be produced by the following: $|f(x) − a| < ε$
 * produces: $|f(x) − a| < ε$

within tables
Fields within a table may be delimited either with a double vertical bar ("||"), or when at the beginning of a line, by single vertical bar ("|"). However, when using the single vertical bar convention, and the first character in a table field is the mathematical symbol absolute value bar, the character will be wrongly interpreted as part of the table's field delimiter, and so will not display. In such cases, delimit that table field using the 'two vertical bar' convention, even though it is at the beginning of a line.

Parameters
The following parameters are optional: $1 + 2 = 3$
 * – This will render the formula in a bigger fontsize, increased to 165%.
 * – Use this to specify your own fontsize.
 * produces: $1 + 2 = 3$
