This glossary will help you build complex mathematical equations using the Tex markup language. This will involve using @@ or $$ before and after the expression to display the desired results.

03 FONT STYLES

\large (all lower case letters)

  • Everthing following the \large command will be output in the large font size until the system encounters another font size command.
  • Note: This command is case sensitive, since large, Large and LARGE are different sizes! 
  • Ex.: $$\large~3x$$ gives \large~3x

\normalsize

  • Everthing following the \normalsize command will be output in the smallest predefined font size until the system encounters another font size command.
  • \normalsize is the default font size, i.e. the size automatically chosen if there is no font size command
  • Ex.: $$\normalsize~3x$$ gives \normalsize~3x

\small

  • \small
  • Ex.: $$\small~3x$$ gives \small~3x

\tiny

  • Everthing following the \tiny command will be output in the smallest predefined font size until the system encounters another font size command.
  • Ex.: $$\tiny~3x$$ gives \tiny~3x

absolute font sizes (overview)

Absolute Font Sizes
CommandExampleResult
\tiny$$\tiny 3x$$\tiny 3x
\small$$\small 3x$$\small 3x
\normalsize (default)$$\normalsize 3x$$ or just $$3x$$\normalsize 3x
\large$$\large 3x$$\large 3x
\Large$$\Large 3x$$\Large 3x
\LARGE$$\LARGE 3x$$\LARGE 3x
   

\huge and \Huge are not supported by the mimeTeX filter

  

04 DELIMITERS (PARENTHESES, BRACES,...)

angle bracket

  • Syntax: \left<...\right>
  • Ex.: $$\left<f,g\right>$$ gives

\left

braces

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

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

delimiters (overview)

\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.

double vertical line (norm symbol)

  • Syntax: \left\|...\right\|
  • Exp.: $$\left\|af\right\| = \left|a\right|\left\|f\right\|$$ gives

\left\|af\right\| = \left|a\right|\left\|f\right\|

left only brace

  • Syntax: \left{...\right.  (note the dot at the end!)
  • Ex.: $$f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.$$ gives

f(x)=\left{{x^2, \rm~if x>-1\atop~0, \rm~else}\right.

(\rm~something switches to roman style)
