Ayuda:TeX

Este artículo no puede con tanto mediawiki y tarda un huevo en cargar. Así que mientras esperas que salga todo te da tiempo a descargar mucho pr0n tomarte un cafetito.

Hola, cabroncete/a. Solo hay dos razones para que estés aquí.

1. Estás más perdido que una patata en una pescadería.
2. Quieres aprender a escribir formulas tan molonas como está: $34^{2}+\infty {\sqrt[{7}]{\frac {4_{3}51}{f_{\aleph }}}}-\pi _{y}*{\frac {27_{3}^{24}}{\omega }}+\int _{\vert x-x_{0}\vert <X_{0}}\Phi$

Si tu caso es el primero largate ahora mismo pulsa atrás en tu navegador. Si es el segundo sigue leyendo.

Lo básico

Para empezar un TeX se puede hacer pulsando el botón Archivo:Math icon.png (sí, el que está entre la bocina y la W tachada) o escribiendo el código entre las etiquetas <math></math>.

Bueno lo siguiente es saber poner los códigos como es debido o te saldrán las archiconocidas letritas rojas: Error al representar (error de sintaxis): {\displaystyle {srjgnþg}}}đg\} . Para evitarlo es necesario que sepas los códigos de TeX. Y de eso va esta ayuda por si aun no te has enterado.

Códigos de formulas

Por fin los dichosos códigos ya era hora...

Fracciones

\frac{2}{4} o {2 \over 4}

${\frac {2}{4}}\,\!$

Raíces

\sqrt{2}	${\sqrt {2}}$
\sqrt[n]{x}	${\sqrt[{n}]{x}}\,\!$

Super y subíndices

a^2	$a^{2}$	$a^{2}\,\!$
a_2	$a_{2}$	$a_{2}\,\!$
x_2^3	$x_{2}^{3}\,\!$
a^{2+2}	$a^{2+2}$	$a^{2+2}\,\!$
a_{i,j}	$a_{i,j}$	$a_{i,j}\,\!$

Subrayado, sobrerrayado y llaves

\hat a \; \bar b \; \vec c \; \overrightarrow{a b} \; \overleftarrow{c d} \; \widehat{d e f} \; \overline{g h i} \; \underline{j k l}

${\hat {a}}\;{\bar {b}}\;{\vec {c}}\;{\overrightarrow {ab}}\;{\overleftarrow {cd}}\;{\widehat {def}}\;{\overline {ghi}}\;{\underline {jkl}}\,\!$

Códigos de fuentes

Para escribir en raro.

Acentos raros

\acute{a} \quad \grave{a} \quad \breve{a} \quad \check{a} \quad \tilde{a}

Poniendo expresiones grandes entre paréntesis, corchetes, etcétera

Usalos para encerrar las fórmulas y que no salgan. Mwahahahaha. ¡Eh! ¡Qué se escapa!

Característica	Sintaxis	Cómo se ve renderizado
Mal	( \frac{1}{2} )	$({\frac {1}{2}})\,\!$
Bien	\left ( \frac{1}{2} \right )	$\left({\frac {1}{2}}\right)\,\!$

Pueden usarse varios delimitadores con \left y \right:

Paréntesis

\left ( \frac{a}{b} \right )

$\left({\frac {a}{b}}\right)\,\!$

Corchetes

\left [ \frac{a}{b} \right ] \quad \left \lbrack \frac{a}{b} \right \rbrack

$\left[{\frac {a}{b}}\right]\quad \left\lbrack {\frac {a}{b}}\right\rbrack \,\!$

Llaves

\left \{ \frac{a}{b} \right \} \quad \left \lbrace \frac{a}{b} \right \rbrace

$\left\{{\frac {a}{b}}\right\}\quad \left\lbrace {\frac {a}{b}}\right\rbrace \,\!$

Ángulos (<, >)

\left \langle \frac{a}{b} \right \rangle

$\left\langle {\frac {a}{b}}\right\rangle \,\!$

Barras simples y dobles

\left | \frac{a}{b} \right \vert \left \Vert \frac{c}{d} \right \|

$\left|{\frac {a}{b}}\right\vert \left\Vert {\frac {c}{d}}\right\|\,\!$

Redondeo inferior y superior

\left \lfloor \frac{a}{b} \right \rfloor \left \lceil \frac{c}{d} \right \rceil

$\left\lfloor {\frac {a}{b}}\right\rfloor \left\lceil {\frac {c}{d}}\right\rceil \,\!$

Barras inclinadas e invertidas

\left / \frac{a}{b} \right \backslash

$\left/{\frac {a}{b}}\right\backslash \,\!$

Flechas simples y dobles

\left \uparrow \frac{a}{b} \right \downarrow \quad \left \Uparrow \frac{a}{b} \right \Downarrow \quad \left \updownarrow \frac{a}{b} \right \Updownarrow

$\left\uparrow {\frac {a}{b}}\right\downarrow \quad \left\Uparrow {\frac {a}{b}}\right\Downarrow \quad \left\updownarrow {\frac {a}{b}}\right\Updownarrow \,\!$

Los delimitadores puede mezclarse

Los delimitadores puede mezclarse, siempre que cada \left vaya cerrado por un \right

\left [ 0,1 \right ) \quad \left \langle \psi \right |

$\left[0,1\right)\left\langle \psi \right|\,\!$

Que no se muestre un delimitador

Usa \left . y \right . si no quieres que se muestre un delimitador

\left . \frac{A}{B} \right \} \to X

$\left.{\frac {A}{B}}\right\}\to X\,\!$

Tamaño de los delimitadores

\big( \Big( \bigg( \Bigg( ... \Bigg] \bigg] \Big] \big]	${\big (}{\Big (}{\bigg (}{\Bigg (}...{\Bigg ]}{\bigg ]}{\Big ]}{\big ]}\,\!$
\big\{ \Big\{ \bigg\{ \Bigg\{ ... \Bigg\rangle \bigg\rangle \Big\rangle \big\rangle	${\big \{}{\Big \{}{\bigg \{}{\Bigg \{}...{\Bigg \rangle }{\bigg \rangle }{\Big \rangle }{\big \rangle }\,\!$
\big\| \Big\| \bigg\| \Bigg\| ... \Bigg| \bigg| \Big| \big|	${\big \|}{\Big \|}{\bigg \|}{\Bigg \|}...{\Bigg |}{\bigg |}{\Big |}{\big |}\,\!$
\big\lfloor \Big\lfloor \bigg\lfloor \Bigg\lfloor ... \Bigg\rceil \bigg\rceil \Big\rceil \big\rceil	${\big \lfloor }{\Big \lfloor }{\bigg \lfloor }{\Bigg \lfloor }...{\Bigg \rceil }{\bigg \rceil }{\Big \rceil }{\big \rceil }\,\!$
\big\uparrow \Big\uparrow \bigg\uparrow \Bigg\uparrow ... \Bigg\Downarrow \bigg\Downarrow \Big\Downarrow \big\Downarrow	${\big \uparrow }{\Big \uparrow }{\bigg \uparrow }{\Bigg \uparrow }...{\Bigg \Downarrow }{\bigg \Downarrow }{\Big \Downarrow }{\big \Downarrow }\,\!$

Color

Ponle colorines a las formulas. Pero no abuses.

{ \color{SkyBlue}3x^2 } - { \color{Red} 5x } + { \color{Green} 2 }

${\color {SkyBlue}3x^{2}}-{\color {Red}5x}+{\color {Green}2}$

{ \color{BrickRed} x } = \frac{ { \color{Red} -b} \pm \sqrt{ \color{Magenta} b^2-4ac } }{ \color{Green} 2a}

${\color {BrickRed}x}={\frac {{\color {Red}-b}\pm {\sqrt {\color {Magenta}b^{2}-4ac}}}{\color {Green}2a}}$
