This board is for the discussion of
mathematics.
Equations can be embedded in multiple ways:
\eqn{...}
or
\math{...}
command substitutions
\[ ... \]
or
\( ... \)
block substitutions
$$ ... $$
or
$ ... $
special block substitutions
\begin{equation} ... \end{equation}
or
\begin{math} ... \end{math}
environments
by starting a line with
,,
or
,eqn
like one commonly would with
>greentext.
Matrices can be embedded by using
\begin{matrix} ... \end{matrix}
or
\begin{array} ... \end{array}
environments in any of the above ways to embed equations, or by starting a line with
,mat
,
,pmat
,
,smat
,bmat
,
,Bmat
,
,vmat
or
,Vmat
and using
&
and
\\
symbols to delineate between columns and rows respectively.
Arrays can be embedded by using
\begin{array}{c|c:c} ... \end{array}
environment in any of the above ways to embed equations, or by starting a line with
,arr{c|c:c}
and using
&
and
\\
symbols to delineate between columns and rows respectively.
NOTE:
c|c:c
is only one example of vertical separation (solid and dotted). Horizontal separation can be accomplished by using
\hline
or
\hdashline
after
\\
.
Alignments can be done by using
\begin{aligned} ... \end{aligned}
in any of the above ways to embed equations, or by starting a line with
,align
and then using
\\
symbols to start new lines and using
&
symbol to specify how to align each line (usually, you want it attached to the equals sign, like
&=
).`
