Template:Tmath/doc

This template wraps a math expression written in TeX code between <math>...</math> tags using the {{#tag:}} parser function magic word. Intended to be used for very short expressions like variables.

Neither display="inline" nor TeX math mode textstyle is set by this template.

Usage

{{tmath|expression}}

Examples

• {{tmath|a}} gives $a$

• {{tmath|\pi}} gives $\pi$

• {{tmath|x_0}} gives $x_{0}$

The template is intended to be used for very short LaTeX mathematical expressions like variables. It is more cumbersome to use for equations or other expressions containing special signs that have to be escaped, like the equal sign = with {{=}} and the vertical pipe | with {{!}}:

• {{tmath|E {{=}} mc^2}} gives $E=mc^{2}$

• {{tmath|x {{=}} {{!}} \vec x {{!}} }} gives $x=|{\vec {x}}|$

Use braces { and } with caution

Apart from using the {{(}} and {{)}} templates to get { and }, you may use the braces { and } as long as { is not preceded or followed by another {, and } is not preceded or followed by another }, e.g.

• {{tmath|x {{=}} {{!}} \vec{x} {{!}} }} gives $x=|{\vec {x}}|$

• {{tmath|\zeta(2) {{=}} \frac{\pi^2}{6} }} parses (you added that space!) to $\zeta (2)={\frac {\pi ^{2}}{6}}$

• {{tmath|\zeta(2) {{=}} \frac{\pi^2}{6}}} fails to parse (you forgot that space!), v.g. Failed to parse (SVG with PNG fallback (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \zeta(2) = \frac{\pi^2}{6} }

• {{tmath|\frac{1}{ x^{2n+1} } }} parses (you added all those spaces!) to ${\frac {1}{x^{2n+1}}}$

• {{tmath|\frac{1}{x^{2n+1}} }} fails to parse (you forgot some of those spaces!), v.g. Failed to parse (syntax error): {\displaystyle \frac{1}{x^{2n+1} }}
