## 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.

(with specific sizing):$$x_{\small1}=a_{\small{m+2n}}$$gives $x_{\small1}=a_{\small{m+2n}}$ • Combine subscripting with superscripting (command character "^"). Syntax: Expr_{subExpr}^{supExpr}. • Ex.:$$A_{\small{i,j,k}}^{\small{-n+2}}$$gives $A_{\small{i,j,k}}^{\small{-n+2}}$ #### 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 $\bigsum_{i=k}^{n}$ 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 $\large\sum_{\small{i=1}}^{\small{n}}$  Keyword(s): big sum #### 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 $x^2$ • Ex.:$$a^{m+2n}$$gives $a^{m+2n}$ • Ex. (with specific sizing):$$x^{\small2}=a^{\small{m+2n}}$$gives $x^{\small2}=a^{\small{m+2n}}$ • Combine superscripting with subscripting (command character "_"). Syntax: Expr_{subExpr}^{supExpr}. • Ex.:$$A_{\small{i,j,k}}^{\small{-n+2}}$$gives $A_{\small{i,j,k}}^{\small{-n+2}}$ ### T #### tau (lower case greek letter)$$\tau$$gives $\tau$ #### TeX $TeX$ notation allows for the expression of ASCII characters to generate formatted graphics output  Keyword(s): TeX #### 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 $\triangle~abc$
 Keyword(s): triangle
