Introduzione

Latex, installato sul server su cui girano i servizi necessari per eseguire il wiki, rende possibile inserire formule nel testo.

Le formule sono convertite in immagine e l'immagine automaticamente incorporata nel testo.

Vediamo alcuni esempi:

• $E=mc^{2}$
• $tg(\theta )={\frac {sin(\theta )}{cos(\theta )}}$

• Un promemoria per la sintassi di LaTex

math

trigonometry

1. $sin(x)^{2}+cos(x)^{2}=1$
2. $sin(x+y)=sin(x)cos(y)+sin(y)cos(x)$
3. $cos(x+y)=cos(x)cos(y)-sin(x)sin(y)$
4. $tg(x)={\frac {sin(x)}{cos(x)}}$
5. $ctg(x)={\frac {cos(x)}{sin(x)}}$

physics

1. $F=ma$
2. $E=mc^{2}$
3. $E=h\nu$

Color

Equations can use color:

• {\color{Blue}x^2}+{\color{YellowOrange}2x}-{\color{OliveGreen}1}

  ${\color {Blue}x^{2}}+{\color {YellowOrange}2x}-{\color {OliveGreen}1}$

• x_{1,2}=\frac{-b\pm\sqrt{\color{Red}b^2-4ac}}{2a}

  $x_{1,2}={\frac {-b\pm {\sqrt {\color {Red}b^{2}-4ac}}}{2a}}$

See here for all named colors supported by LaTeX.

Note that color should not be used as the only way to identify something, because it will become meaningless on black-and-white media or for color-blind people. See en:Wikipedia:Manual of Style#Color coding.

Formatting issues

Spacing

Note that TeX handles most spacing automatically, but you may sometimes want manual control.

Feature	Syntax	How it looks rendered

large space	a\;b	$a\;b$

small space	a\,b	$a\,b$
no space	ab	$ab\,$
small negative space	a\!b	$a\!b$

Alignment with normal text flow

Due to the default css

img.tex { vertical-align: middle; }

an inline expression like $\int _{-N}^{N}e^{x}\,dx$ should look good.

If you need to align it otherwise, use <math style="vertical-align:-100%;">...</math> and play with the vertical-align argument until you get it right; however, how it looks may depend on the browser and the browser settings.

Also note that if you rely on this workaround, if/when the rendering on the server gets fixed in future releases, as a result of this extra manual offset your formulae will suddenly be aligned incorrectly. So use it sparingly, if at all.
