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.

S

square bracket

  • Synatx: \left[...\right]
  • Ex.: $$\left[a,b\right]$$ gives \left[a,b\right]

square root

@@@sqrt{x}@@@  is @@sqrt(x)@@

subscript

underscore $$x_2$$  is   x_2

sum (summation)

  • General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

  • In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
  • Syntax for summation symbol:

$$\bigsum_{i=k}^{n}$$   gives  

\bigsum_{i=k}^{n}

and

$$\sum_{i=k}^{n}$$   gives 

\sum_{i=k}^{n}

  • Use font size commands for a nicer picture:

$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$$   gives  

\LARGE\bigsum_{\small{i=1}}^{\small{n}}

and

$$\large\sum_{\small{i=1}}^{\small{n}}$$   gives 

\large\sum_{\small{i=1}}^{\small{n}}


superscript

$$x^2$$ or $$x^3$$ is x^2 or x^3

T

tau (lower case greek letter)

$$\tau$$ gives \tau

TeX

TeX  notation allows for the expression of ASCII characters to generate formatted graphics output

theta (lower case greek letter)

$$\theta$$ gives \theta

Theta (upper case greek letter)

$$\Theta$$ gives \Theta

times

$$a\times~b$$ gives a\times~b
