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 $$\delta $$ |
|
div (division) $$$x\div~y$$$ gives $$x\div~y$$ |
|
double vertical line (norm symbol) - Syntax: \left\|...\right\|
- Exp.: $$$\left\|af\right\| = \left|a\right|\left\|f\right\|$$$ gives
$$\left\|af\right\| = \left|a\right|\left\|f\right\|$$ |
