Math Notation Help

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.

delimiters (overview)

Delimiters (parentheses, braces, brackets. ...)

\left(... \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.


$$\delta$$ 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 \frac{1}{2}

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\|
