Template:Math/doc

The math template formats HTML, or wikimarkup generated mathematical formulas. 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). The template also prevents line-wrapping.

Usage
Use this template for inline, non-complex formulas as an alternative to using the  tag pair (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: $|f(x) − a| < ε$

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: $1 + 2 = 3$
