#### 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

$$\delta$$ is $\delta$

#### Delta (upper case greek letter)

$$\Delta$$ gives $\Delta$

#### delta (lower case greek letter)

$$\delta$$ gives $\delta$

#### div (division)

$$x\div~y$$ gives $x\div~y$

@@1/2@@   is

#### double vertical line (norm symbol)

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

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