Using MimeTeX 2

As we have already covered the basics of MimeTeX, this page is devoted to the characters you can use.

WARNING: In this Wiki environment, the MimeTeX filter is not controlling the essential rendering of the control sequences. The effects are the same, but they are rendered by another Tex filter. It helps the syntax is almost the same though.

Maths symbols available in Moodle

A number of the characters and symbols below have already been covered in previous pages, but this is a more exhaustive list. There are a number more, but their relevance to K-12 maths is questionable.

Keyboard characters are available as themselves but many characters have a significance in TeX. All command sequences start and end with the $$ i.e. $$ \entire command sequence $$. All control sequences start with the backslash, \, i.e. \times, or \frac{1}{2}, and have no end character. There are a number of different types of charsets available, not just Maths but also scientific sets but these need be installed to your Moodle if you want additional charsets. Unfortunately, MimeTeX is designed for use in Maths, not science, so it may struggle using non-Maths charsets.

Symbols

These are not all the symbols that may be available in MimeTeX, just the ones that I have found to work in Moodle.

\amalg	$\amalg$	\cup	$\cup$	\oplus	$\oplus$	\times	$\times$
\ast	$\ast$	\dagger	$\dagger$	\oslash	$\oslash$	\triangleleft	$\triangleleft$
\bigcirc	$\bigcirc$	\ddagger	$\ddagger$	\otimes	$\otimes$	\triangleright	$\triangleright$
\bigtriangledown	$\bigtriangledown$	\diamond	$\diamond$	\pm	$\pm$	\odot	$\odot$
\bigtriangleup	$\bigtriangleup$	\div	$\div$	\ominus	$\ominus$	\wr	$\wr$
\circ	$\circ$	\wedge	$\wedge$	\vee	$\vee$	\sqcup	$\sqcup$
\leq	$\leq$	\geq	$\geq$	\equiv	$\equiv$	\prec	$\prec$
\succ	$\succ$	\sim	$\sim$	\perp	$\perp$	\preceq	$\preceq$
\succeq	$\succeq$	\simeq	$\simeq$	\mid	$\mid$	\ll	$\ll$
\gg	$\gg$	\asymp	$\asymp$	\parallel	$\parallel$	\subset	$\subset$
\supset	$\supset$	\subseteq	$\subseteq$	\supseteq	$\supseteq$	\approx	$\approx$
\neq	$\neq$	\ni	$\ni$	\notin	$\notin$	\in	$\ni$
\vdash	$\vdash$	\dashv	$\dashv$	\bullet	$\bullet$	\cdot	$\cdot$

Arrows

\leftarrow	$\leftarrow$	\longleftarrow	$\longleftarrow$	\Leftarrow	$\Leftarrow$	\Longleftarrow	$\Longleftarrow$
\rightarrow	$\rightarrow$	\longrightarrow	$\longrightarrow$	\Rightarrow	$\Rightarrow$	\Longrightarrow	$\Longrightarrow$
\uparrow	$\uparrow$	\Uparrow	$\Uparrow$	\downarrow	$\downarrow$	\Downarrow	$\Downarrow$
\leftrightarrow	$\leftrightarrow$	\longleftrightarrow	$\longleftrightarrow$	\updownarrow	$\updownarrow$	\Updownarrow	$\Updownarrow$
\Leftrightarrow	$\Leftrightarrow$	\Longleftrightarrow	$\Longleftrightarrow$	\leftrightharpoon	$\rightleftharpoons$	\Im	$\Im$
\nearrow	$\nearrow$	\nwarrow	$\nwarrow$	\swarrow	$\swarrow$	\searrow	$\searrow$

Delimiters and Maths Constructs

NOTE: Most delimiters and constructs need additional parameters for them to appear appropriately.

\{x	$\{x$	\}	$x|\}$	\rangle	$\rangle$	\langle	$\langle$
\angle	$\angle$	\=	$\|$	\sqrt{ab}	${\sqrt {ab}}$	\sqrt[n]{ab}	${\sqrt[{n}]{ab}}$
\frac{ab}{cd}	${\frac {ab}{cd}}$	\backslash	$\backslash$	\widehat{ab}	${\widehat {ab}}$	\$	$\$$
\overline{ab}	${\overline {ab}}$	\underline{ab}	${\underline {ab}}$	\therefore	$\therefore$	\ddots	$\ddots$
\%	$\%$	\#	$\#$	\vdots	$\vdots$	\emptyset	$\emptyset$

WARNINGS: The & character in LaTeX usually requires a \. In TeX, apparently, it does not. Other packages, AsciiMath, may use it differently again so be careful using it. The copyright character may use the default MimeTeX charset, and produces a copyright notice for John Forkosh Associates. I have been, almost reliably, informed that a particular instruction will produce a different notice though .:)

There are also a number of characters that can be used in MimeTeX but do not render in this page:

Larger \left(x and \right) brackets

\widetilde{ab}

\textdegree or (50)^\circ

Greek Letters

$\alpha$	\alpha	$\beta$	\beta	$\gamma$	\gamma
$\delta$	\delta	$\epsilon$	\epsilon	$\zeta$	\zeta
$\eta$	\eta	$\theta$	\theta	$\iota$	\iota
$\kappa$	\kappa	$\lambda$	\lambda	$\mu$	\mu
$\xi$	\xi	$\pi$	\pi	$\rho$	\rho
$\sigma$	\sigma	$\tau$	\tau	$\upsilon$	\upsilon
$\phi$	\phi	$\chi$	\chi	$\psi$	\psi
$\omega$	\omega	$\Omega$	\Omega	$\Theta$	\Theta
$\Delta$	\Delta	$\Pi$	\Pi	$\Phi$	\Phi

Notable Exceptions

Greek letter omicron. Simply put, omicron is an "o" or an "O".

Fonts

To use a particular font you need to access the font using the same syntax as demonstrated above.

A math calligraphic font:

${\mathcal {ABCDEFGHIJKLMNOPQRSTUVXYZ}}$

or

$$ \mathcal{ABCDEFGHIJKLMNOPQRSTUVXYZ}$$

A Castellar type font:

$\mathbb {ABCDEFGHIJKLMNOPQRSTUVXYZ}$

or

$$ \mathbb{ABCDEFGHIJKLMNOPQRSTUVXYZ}$$

An Old English type font:

${\mathfrak {ABCDEFGHIJKLMNOPQRSTUVXYZ}}$

or

$$ \mathfrak{ABCDEFGHIJKLMNOPQRSTUVXYZ}$$

An italic font:

ABCDEFGHIJKLMNOPQRSTUVXYZ

or

$$ \mathi{ABCDEFGHIJKLMNOPQRSTUVXYZ} $$

A bold-face font:

$\mathbf {ABCDEFGHIJKLMNOPQRSTUVXYZ}$

or

$$ \mathbf{ABCDEFGHIJKLMNOPQRSTUVXYZ} $$
