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 root

  • $$\sqrt{a}$ or $$\sqrt~a$ gives \sqrt~a
  • Use braces for terms with more than one character: $$\sqrt{x+y}$ gives</li></ul><p align="center">\sqrt{x+y}$$


subscript

  • The command character "_" triggers subscription of the following expression(s).
  • For more than one subscripted character put them in braces {...}.
  • Use font sizing commands for appropriate sizing.
  • Ex.:$$x_1$ gives </li></ul><p style="text-align:center;">x_1$$

    • Ex.:$$a_{m+2n}$ gives </li></ul><p style="text-align:center;">a_{m+2n}$$

      • Ex. (with specific sizing):  $$x_{\small1}=a_{\small{m+2n}}$ gives</li></ul><p style="text-align:center;">x_{\small1}=a_{\small{m+2n}}$$

        • Combine subscripting with superscripting (command character "^").
          Syntax: Expr_{subExpr}^{supExpr}.
        • Ex.: $$A_{\small{i,j,k}}^{\small{-n+2}}$ gives</li></ul><p style="text-align:center;">A_{\small{i,j,k}}^{\small{-n+2}}$$


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:

$$\bigsum_{i=k}^{n}$   gives   </p><p align="center">\bigsum_{i=k}^{n} </p><p align="center">and</p><p align="center">$$\sum_{i=k}^{n}$   gives 

\sum_{i=k}^{n}

  • Use font size commands for a nicer picture:

$$\LARGE\bigsum_{\small{i=1}}^{\small{n}}$   gives   </p><p></p><p align="center">\LARGE\bigsum_{\small{i=1}}^{\small{n}} </p><p align="left"></p><p align="center">and</p><p align="center">$$\large\sum_{\small{i=1}}^{\small{n}}$   gives 

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


superscript

  • The command character "^" triggers superscription of the following expression(s).
  • For more than one superscripted character put them in braces {...}.
  • Use font sizing commands for appropriate sizing.
  • Ex.: $$x^2$ gives </li></ul><p style="text-align:center;">x^2$$

    • Ex.: $$a^{m+2n}$ gives </li></ul><p style="text-align:center;">a^{m+2n}$$

      • Ex. (with specific sizing): $$x^{\small2}=a^{\small{m+2n}}$ gives</li></ul><p style="text-align:center;">x^{\small2}=a^{\small{m+2n}}$$

        • Combine superscripting with subscripting (command character "_").
          Syntax: Expr_{subExpr}^{supExpr}.
        • Ex.: $$A_{\small{i,j,k}}^{\small{-n+2}}$ gives</li></ul><p style="text-align:center;">A_{\small{i,j,k}}^{\small{-n+2}}$$


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

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

triangle

$$\triangle~abc$ gives \triangle~abc$$
