## LaTeX Glossary

My.SUPA has been setup to allow maths to be written quickly using LaTeX notation. This can be included anywhere you see a text box in your course area -- including news or social forums, web pages and wikis. The format for entering LaTeX in My.SUPA is to wrap the code between two pairs of dollar signs. $$a=b+c$$

If you are looking at this for the first time, please read the entries under 01 Getting Started for an overview. The list of entries may be viewed by categories or alphabetically.

### B

#### beta (lower case greek letter)

$$\beta$$ gives $\beta$

#### braces

• Syntax: \left{...\right}
• Ex.: $$M=\left{a, b, c\right}$$ gives

$M=\left{a, b, c\right}$

### C

#### cdot (multiplication)

$$a\cdot~b$$ gives $a\cdot~b$

#### chi (lower case greek letter)

$$\chi$$ gives $\chi$

#### constants

• Numbers in formulas are interpreted as constants and they are rendered in non-italic roman font face, which is a widely used convention.
• Following this convention, variables are shown in italic.
• Exp.: $$f(x)=3a+x$$ gives

$f(x)=3a+x$

#### contour integral

• General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

• In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
• Syntax for the contour integral symbol:

$$\bigoint_{0}^{\infty}$$   gives

$\bigoint_{0}^{\infty}$

and

$$\oint_{0}^{\infty}$$   gives

$\oint_{0}^{\infty}$

• Use font size commands for a nicer picture:

$$\LARGE\bigoint_{\small0}^{\small\infty}$$   gives

$\LARGE\bigoint_{\small0}^{\small\infty}$

and

$$\large\oint_{\small0}^{\small\infty}$$   gives

$\large\oint_{\small0}^{\small\infty}$

#### coproduct

• General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

• In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
• Note: mimeTeX seems currently only to support the \bigcoprod command.
• Syntax for coproduct symbol:

$$\bigcoprod_{i=k}^{n}$$   gives

$\bigcoprod_{i=k}^{n}$

• Use font size commands for a nicer picture:

$$\LARGE\bigcoprod_{\small{i=k}}^{\small~n}$$   gives

$\LARGE\bigcoprod_{\small{i=k}}^{\small~n}$

### D

#### delimiters (overview)

 Delimiters (parentheses, braces, brackets. ...) Command Example Result \left(... \right) $$2\left(a+b\right)$$ $2~\left(a+b\right)$ \left[... \right] $$\left[a^2+b^2~\right]$$ $\left[a^2+b^2~\right]$ \left{... \right} $$\left{x^2, x^3, x^4,... \right}$$ $\left{x^2, x^3, x^4,... \right}$ \left\langle... \right\rangle $$\left\langle a,b~\right\rangle$$ $\left\langle a,b~\right\rangle$ \left| ... \right| $$\det\left|\array{a&b\\c&d}\right|$$ $\det\left|\array{a&b\\c&d}\right|$ \left\| ... \right\| $$\left\|f~\right\|$$ $\left\|f~\right\|$ \left{ ... \right.(note the dot!) $$f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.$$(\rm switches to roman style) $f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.$ \left.{ ... \right\}(note the dot!) $$\left.{{\rm~term1\atop\rm~term2}\right}=y$$ $\left.{{\rm~term1\atop \rm~term2}\right}=y$

Note: The delimiters are automatically sizes.

#### Delta (upper case greek letter)

$$\Delta$$ gives $\Delta$

#### delta (lower case greek letter)

$$\delta$$ gives $\delta$
