They behave similarly to the built-in -\texttt{equation} and \texttt{amsmath}'s \texttt{align} environments and can essentially -be used as drop-in replacements. The main difference is that equation numbers are -handled differently: equations are numbered if and only if they have a \verb|\label|, -so there is no need for starred versions. This also applies to individual lines in -a multiline equation. Also, the \texttt{equs} environment supports blocks of equation -with more - -Since \texttt{mhequ} redefines the \verb|\tag| and \verb|\intertext| commands, it should -always be loaded \textit{after} the \texttt{amsmath} package. However, these -two commands should still behave correctly inside the \texttt{amsmath} environments. -The rest of this document demonstrates the usage of the \texttt{mhequ} package, -it is easiest to just read the source code of this document to see how it works. -See also the description given at the start of the file \texttt{mhequ.sty}. - -Here is a simple labelled equation: -\begin{equ}[onelab] - e^{i\pi} + 1 = 0 \;. -\end{equ} -Removing or adding the label does not require a change of environment: -\begin{equ} - e^{i\pi} + 1 = 0 \;. -\end{equ} -However, if the option \texttt{numberall} is set, then every single -equation is numbered. -A simple list of equations can be displayed either with one number -per equation -\begin{align} - f(x) &= \sin(x) + 1\;, \label{e:equ1}\\ - h(x) &= f(x) + g(x) -3\;, \label{e:equ3} -\end{align} -\begin{equs} - f(x) &= \sin(x) + 1\;, \label{e:equ1}\\ - h(x) &= f(x) + g(x) -3\;, \label{e:equ3} -\end{equs} -or with one number for the whole list -\begin{equs}[e:block] - f(x) &= \sin(x) + 1\;, \\ - h(x) &= f(x) + g(x) -3\;. -\end{equs} -Of course, it can also have no number at all: -\begin{equs} - f(x) &= \sin(x) + 1\;, \\ - h(x) &= f(x) + g(x) -3\;. -\end{equs} -The command \verb|\minilab{label_name}| allows us to create a counter for the lines -in a block of equations. -\minilab{otherlabel} -\begin{equs} - f(x) &= \sin(x) + 1\;, \label{e:f}\\ - g(x) &= \cos(x) - x^2 + 4\;,\label{e:g}\\[3mm] - h(x) &= f(x) + g(x) -3\;. \label{e:h} -\end{equs} -One can refer to the whole block \eref{otherlabel} or to one -line, like \eref{e:f} for example. -It is possible to use any tag one likes with the \verb|\tag{displayed_tag}| -command -\begin{equ}[mylabel] - x = y\;, \tag{$\star$} -\end{equ} -which in this case was used as \verb|\tag{$\star$}|. -Such an equation can be referred to as usual: \eref{mylabel}. -Of course, \texttt{mhequ} can be used in conjunction with the usual \texttt{equation} environment, -but \texttt{mhequ} is great, so why would you want to do this? -\begin{equation} - x=y+z -\end{equation} -Typesetting several columns of equations is quite easy and doesn't require 10 different environments -with awkward names: -\begin{equs} - x&=y+z &\qquad a&= b+c &\qquad x&= v \label{laba}\\ - x&=y+z &\qquad a&= b+c &\qquad x&= u+1\tag{\ref{laba}'}\label{labtag}\\ - \multicol{4}{\text{(multicol)}} &\qquad x&=y \\ - a&= b &\multicol{4}{\qquad\text{(multicol)}} \\ - x&=y+z &\qquad a^2&= (b-c)^3 +y \\ -\intertext{and also (this is some \texttt{\string\intertext})} - x&=y+z &\qquad a&= (b+c)^2 - 5 &\qquad \ell&= m\label{labb} -\end{equs} -We can even extend the block \eref{otherlabel} much later -using the \verb|\minilab{label_name}| command: -\minilab{otherlabel} -\begin{equs} - x&=y+z &\quad x&=y+z &\quad f(x)&= b\label{e:x1}\\ - x&=y+z & x&=y+z &\quad g(x)&= b\label{e:x2} \\ - \multicol{6}{\sin^2 x + \cos^2 x = 1} \label{e:x3} -\end{equs} -It is possible to change the type of subnumbering and to use the -\texttt{\string\text} command without having to load \texttt{amstext}: -\setlabtype{Alph} -\minilab{alab} -\begin{equs} - I_1 &= \int_a^b g(x)\,dx\;,&\quad&\text{(First equation)} \label{e:1}\\ - I_2 &= \int_a^b g(x^2-1)\,dx\;.&\quad&\text{(Second equation)} \label{e:2} -\end{equs} - -\end{document}
