Relations
Symbol | Command | Symbol | Command | Symbol | Command |
---|---|---|---|---|---|
\le | \ge | \neq | |||
\sim | \ll | \gg | |||
\doteq | \simeq | \subset | |||
\supset | \approx | \asymp | |||
\subseteq | \supseteq | \cong | |||
\smile | \sqsubset | \sqsupset | |||
\equiv | \frown | \sqsubseteq | |||
\sqsupseteq | \propto | \bowtie | |||
\in | \ni | \prec | |||
\succ | \vdash | \dashv | |||
\preceq | \succeq | \models | |||
\perp | \parallel | \| | |||
\mid |
Negations of many of these relations can be formed by just putting \not before the symbol, or by slipping an n between the \ and the word. Here are a few examples, plus a few other negations; it works for many of the others as well.
Symbol | Command | Symbol | Command | Symbol | Command |
---|---|---|---|---|---|
\nmid | \nleq | \ngeq | |||
\nsim | \ncong | \nparallel | |||
\not< | \not> | \not= | |||
\not\le | \not\ge | \not\sim | |||
\not\approx | \not\cong | \not\equiv | |||
\not\parallel | \nless | \ngtr | |||
\lneq | \gneq | \lnsim | |||
\lneqq | \gneqq |
To use other relations not listed here, such as =, >, and <, in LaTeX, you may just use the symbols on your keyboard.

\uparrow | \Uparrow | ||
\downarrow | \Downarrow | ||
\updownarrow | \Updownarrow | ||
\nearrow | \searrow | ||
\swarrow | \nwarrow |
(For those of you who hate typing long strings of letters, \iff and \implies can be used in place of \Longleftrightarrow and \Longrightarrow respectively.)
Dots
Accents
Symbol | Command | Symbol | Command | Symbol | Command | Symbol | Command |
---|
Symbol | Command | Symbol | Command | Symbol | Command |
---|---|---|---|---|---|
\hat{x} | \check{x} | \dot{x} | |||
\breve{x} | \acute{x} | \ddot{x} | |||
\grave{x} | \tilde{x} | \mathring{x} | |||
\bar{x} | \vec{x} |
When applying accents to i and j, you can use \imath and \jmath to keep the dots from interfering with the accents:
Symbol | Command | Symbol | Command |
---|---|---|---|
\vec{\jmath} | \tilde{\imath} |
\tilde and \hat have wide versions that allow you to accent an expression:
Symbol | Command | Symbol | Command |
---|---|---|---|
\widehat{3+x} | \widetilde{abc} |
Others
Command Symbols
Some symbols are used in commands so they need to be treated in a special way.
Symbol | Command | Symbol | Command | Symbol | Command | Symbol | Command |
---|---|---|---|---|---|---|---|
\textdollar | \& | \% | \# | ||||
\_ | \{ | \} | \backslash |
(Warning: Using $ for will result in . This is a bug as far as we know. Depending on the version of LaTex this is not always a problem.)

Bracketing SymbolsIn mathematics, sometimes we need to enclose expressions in brackets or braces or parentheses. Some of these work just as you'd imagine in LaTeX; type ( and ) for parentheses, [ and ] for brackets, and | and | for absolute value. However, other symbols have special commands:
You might notice that if you use any of these to typeset an expression that is vertically large, like
the parentheses don't come out the right size: If we put \left and \right before the relevant parentheses, we get a prettier expression:
gives \left and \right can also be used to resize the following symbols:
Multi-Size SymbolsSome symbols render differently in inline math mode and in display mode. Display mode occurs when you use \[...\] or $$...$$, or environments like In each of the following, the two images show the symbol in display mode, then in inline mode.
