\chapter{Various features regarding alignment}
\label{cha:vari-feat-regard}
-\section{Arrow between lines}
-\label{sec:arrow-between-lines}
-Sometimes lines in an alignment are related in the sense of \emph{from
-which it follows}, usually indicated by $\Rightarrow$. We would like
-to place this between the lines in a nice way. The following macro is
-due to Morten Høgholm.
-\begin{syntax}
- \markup{ArrowBetweenLines}\oarg{arrow}
- \markup{ArrowBetweenLines*}\oarg{arrow}
-\end{syntax}
-Simply hold back one column of alignment for the arrow:
-\begin{sourcedisplay}
-\begin{alignat}{2}
- && f(x) & = \dbx[2cm] \\
- \ArrowBetweenLines
- && g(x) & = - \dbx[2cm] \\
- \ArrowBetweenLines[\Downarrow]
- && h(x) & = 0
-\end{alignat}
-\end{sourcedisplay}
-Note the height of the arrow line and that the line automatically does
-not contain equation numbers. The stared version can be used to place
-the arrows on the right. Though several alignment columns on each line
-might become a problem.
-\begin{sourcedisplay}
-\begin{alignat}{2}
- f(x) & = \dbx[2cm] \\
- \ArrowBetweenLines*
- g(x) & = - \dbx[2cm] \\
- \ArrowBetweenLines*[\Downarrow]
- h(x) & = 0
-\end{alignat}
-\end{sourcedisplay}
-\noindent\note{This macro have been added to the mathtools package, and will be
- available with the next mathtools release, afterwhich it will be
- removed from this package.}

-\section{Switch dead space}
-\label{sec:switch-dead-space}
-
-The standard \markup[nomk,env]{equation} environment has the feature
-that if the text before it is short and the formula likewise, then the
-drop between the preceding text and the formula will be
-\markup[length,nomk]{abovedisplayshortskip} instead of the usual
-\markup[length,nomk]{abovedisplayskip}. The macros from the
-\markup[nomk,sty]{amsmath} package does not have this feature (except
-\markup[nomk,env]{equation*}).
-\begin{sourcedisplay}
-text
-\[ a=b \]
-text
-\begin{align*}
- a=b
-\end{align*}
-\end{sourcedisplay}
-The macro \markup{SwapDeadSpace} can simulate this feature
-\begin{sourcedisplay}
-text
-\[ a=b \]
-text
-\begin{align*}
- \SwapDeadSpace
- a=b
-\end{align*}
-\end{sourcedisplay}

-\section{Left alignment}
-\label{sec:left-alignment}
-
-In \cite{swanson}, Ellen Swanson presents some recommendations
-regarding how to arrange displayed formulas. One thing she recommends
-is alignment to the left and with all subsequent lines indented by
-2\,em.
-\begin{align*}
-\malign[-2pt]{2}
- &\dbx[5cm]=\dbx[4cm]\\
- &\qquad{}=\dbx[6cm]\\
- &\qquad{}=\dbx[5cm]\,.
-\end{align*}
-or
-\begin{align*}
-\malign[-2pt]{2}
- &\dbx[8cm]\\
- &\qquad{}=\dbx[4cm]\\
- &\qquad{}=\dbx[6cm]\,.
-\end{align*}
-or
-\begin{align*}
-\malign[-2pt]{2}
- &\dbx[5cm]=\dbx[4cm]\\
- &\qquad{}+\dbx[6cm]\\
- &\qquad{}\times\dbx[5cm]\,.
-\end{align*}
-and
-\begin{align*}
-\malign[-2pt]{2}
- &\dbx[8cm]\\
- &\qquad{}-\dbx[4cm]\\
- &\qquad{}\otimes\dbx[6cm]\,.
-\end{align*}
-But having to do all those indentations by hand quickly becomes quite
-tedious. Instead, align everything to the left, and pull back the first
-line. This is what the following macro does.
-
-\note{Please note that this macro have been added to the
-mathtools package and will be available with the next release of
-mathtools, afterwhich it will be removed from this package.}
-\begin{syntax}
- \markup{MoveEqLeft}\oarg{number}
-\end{syntax}
-The optional argument is a number (without unit, em will be used)
-indicating the amount of indentation. 2\,em is the default. Now simply
-use \markup[nomk]{MoveEqLeft} instead of the >>\texttt{\&}<< on the
-first line.
-\begin{sourcedisplay}
-\begin{align*}
- \MoveEqLeft f(x) + g(x) + \dbx[4cm] \\
- & = \dbx[5cm] \\
- & = \dbx[5cm]
-\end{align*}
-\end{sourcedisplay}
-The optional argument is usually used whenever the alignment is moved
-to the right of the equal signs.
-\begin{sourcedisplay}
-\begin{align*}
- \MoveEqLeft[3] f(x) + g(x) + \dbx[4cm] \\
- ={} & \dbx[5cm] \\
- & + \dbx[5cm]
-\end{align*}
-\end{sourcedisplay}

\chapter{Declaring sets}

+\emph{This still needs some work}

It is a good idea to avoid the one (or two) letter shortcuts for sets
etc., e.g.\ \verb+\R+ for \verb+\mathbb{R}+, it can cause problems
when co-writing articles with people with other naming habits.
