## 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.

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$$x^2$$or$$x^3$$is $x^2$ or $x^3$  Keyword(s): superscript^ ### 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$$\Delta is $\Delta$
