## 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.

You must use one of the defined math spaces to get a visible (extra) space.  Keyword(s): spaces in formulas, predefined spaces #### mathematics expression • A valid expression inside the 's is rendered as mathematics in an inserted gif image. • Ex.:$$x=y^2$$creates $x=y^2$  Keyword(s): mathematics expression #### matrix • An (m,n)-matrix is considered as an array of m*n elements, where the elements of a column are separated by "&" and the rows by "\\". • Syntax for an (m,n)-matrix: \begin{array}{colformat}a11&...&a1n\\a21&...&a2n\\... \\am1&...&amn \end{array} where colformat defines the format of each of the n columns: l for left, r for right and c for center (hence {ccccc} defines for a (m,5)-matrix in which all columns are centered) • Ex.:$$\left(\begin{array}{lcr}a_{\tiny1}+d & a_{\tiny2}+d & a_{\tiny3}+d \\ b_{\tiny1}& b_{\tiny2}& b_{\tiny3} \\ c_{\tiny1} & c_{\tiny2} & c_{\tiny3} \end{array}\right)gives $\left(\begin{array}{lcr}a_{\tiny1}+d & a_{\tiny2}+d & a_{\tiny3}+d \\ b_{\tiny1}& b_{\tiny2}& b_{\tiny3} \\ c_{\tiny1} & c_{\tiny2} & c_{\tiny3} \end{array}\right)$ Note in the example above that "lcr" has the effect that column 1 is left aligned, column 2 centered and colums 3 right aligned.  Keyword(s): matrix, array #### minus-$$is $-$  Keyword(s): -minus #### minus plus$$\mp~a$$gives $\mp~a$ #### mu (lower case greek letter)$$\mu$$gives $\mu$ #### multiplication$$x*y=z$$is $x*y=z$  Keyword(s): multiplicationmultiply #### multiplication (with cdot)$$a\cdot~b gives $a\cdot~b$
 Keyword(s): cdot
