+We will indicate the amplitude and phase relationship through the use
+of complex notation: a complex number is used to indicate only the
+amplitude and phase of voltages and currents in the circuit (since the
+sinusoidal time variation factor is common to all terms).  For
+example, a circuit described by the equation
+\[
+i(t)=I_{0}\cos(\omega t+\theta)
+\]
+can be written in complex exponential form as
+\[
+i(t)=\Re\{I_{0}e^{j(\omega t+\theta)}\}=
+\Re\{I_{0}e^{j\theta}e^{j\omega t}\},
+\]
+and in polar complex form as
+\[
+i(t)=\Re\{I_{0}\phase{\theta}e^{j\omega t}\}.
+\]
+Finally, we can simplify the notation by dropping the implied
+$e^{j\omega t}$ term and the $\Re\{~\}$ operator, leaving the phasor
+notation:
+\[
+\mathbf{I}=I_{0}\phase{\theta}=I_{0}e^{j\theta}=
+I_{0}(\cos\theta+j\sin\theta),
+\]
+where the boldface $\mathbf{I}$ reminds us that the phasor quantity
+$\mathbf{I}$ is a complex number.  The important advantage of this
+approach is that the mathematics involves mostly simple algebraic
+operations on the magnitudes and phases.
+
+It is interesting to look at the complex ratio of phasor voltage and
+phasor current, $\mathbf{V}\!/\mathbf{I}$, which is called the
+\emph{impedance}~$\mathbf{Z}$.  For the basic circuit elements we
+find:
+\begin{itemize}
+\item Resistor, $R$: $\mathbf{Z}=R$,
+\item Inductor, $L$: $\mathbf{Z}=j\omega L=
+  \omega L\phase{90^{\circ}}$,
+\item Capacitor, $C$: $\displaystyle\mathbf{Z}=\frac{1}{j\omega C}=
+  -j\frac{1}{\omega C}=\frac{1}{\omega C}\phase{-90^{\circ}}$.

+% \section{Introduction}
+%
+% In electrotechnics it is common a notation for variables taking on
+% complex values. First of all any nonzero complex number $z$ admits a
+% unique representation as
+% \[
+% z=\varrho(\cos\alpha+i\sin\alpha)
+% \]
+% where $\varrho$ is a positive real number and $\alpha$ is a real
+% number in the interval $[0,2\pi)$. In technical applications $\alpha$
+% is expressed in degrees, with figures such as $30^{\circ}$. The
+% conversion is very easy by considering $^{\circ}$ as the
+% multiplicative constant $\pi/180$. By Euler formulas, we can write
+% \[
+% z=\varrho(\cos\alpha+i\sin\alpha)=\varrho e^{i\alpha}
+% \]
+% but Steinmetz, in the nineteenth century, started to express this in a
+% simplified form:
+% \[
+% z=\varrho\angle\alpha
+% \]
+% which has however the disadvantage to be difficult to interpret when
+% the angle is the result of some algebraic expression. This is where
+% this package helps: indeed we can write
+% \iffalse
+%<*verb>
+% \fi
+\begin{verbatim}
+z=\varrho\phase{\alpha+\beta}
+\end{verbatim}
+% \iffalse
+%</verb>
+% \fi
+% which gives
+% \[
+% z=\varrho\phase{\alpha+\beta}
+% \]
+% making it clear what is the angle to consider. Some textbooks in
+% electrotechnics use this notation and some users asked how to
+% produce it in {\LaTeX}.
+%
+%
+% \subsection*{Dependencies}
+%
+% Note that this package requires \textsf{pict2e}, so a fairly recent
+% version of {\LaTeX} is needed. In order to typeset this document,
+% you have to generate the package file, by running {\LaTeX} on
+% \texttt{steinmetz.ins}, unless it's already in your distribution.
+%
+% \section{Commands}
+%
+% \DescribeMacro{\phase}
+% This package provides only one command, \cmdname{phase}, which takes
+% as argument the angle to be enclosed in the Steinmetz symbol. It may
+% receive also an optional argument, an integer number from $0$ to $3$
+% (default~$1$). This optional argument tells {\LaTeX} to typeset the
+% angle in the various mathematical styles, as exemplified in
+% table~\ref{optional}.
+%
+% \begin{table}
+% \caption{Results from the various choices of the optional argument
+%   to \protect\cmdname{phase}}\label{optional}
+% \medskip\centering\let\?\bigstrut
+% \begin{tabular}{ll}
+% \hline
+% Command & Result\\
+% \hline
+% \?\verb|A\phase{\alpha}| & $\phase{\alpha}$ \\
+% \?\verb|A\phase{30^{\circ}}| & $A\phase{30^{\circ}}$ \\
+% \?\verb|A\phase[0]{\alpha}| & $A\phase[0]{\alpha}$ \\
+% \?\verb|A\phase[1]{\alpha}| & $A\phase[1]{\alpha}$ \\
+% \?\verb|A\phase[2]{\alpha}| & $A\phase[2]{\alpha}$ \\
+% \?\verb|A\phase[3]{\alpha}| & $A\phase[3]{\alpha}$ \\
+% \?\verb|A\phase[0]{\frac{\alpha}{2}}| &
+% $A\phase[0]{\frac{\alpha}{2}}$ \\
+% \?\verb|A\phase[1]{\frac{\alpha}{2}}| &
+% $A\phase[1]{\frac{\alpha}{2}}$ \\
+% \?\verb|A\phase[2]{\frac{\alpha}{2}}| &
+% $A\phase[2]{\frac{\alpha}{2}}$ \\
+% \?\verb|A\phase[3]{\frac{\alpha}{2}}| &
+% $A\phase[3]{\frac{\alpha}{2}}$ \\
+% \hline
+% \end{tabular}
+% \end{table}
+%
+% Recall that the command \cmdname{phase} should be given only in math
+% mode. Since the command is usually written in display or text style,
+% it should be uncommon to need the optional argument, unless you have
+% to force a particular style for fractions.
+%
+% If you have more than one of these symbols in a row, it can help
+% alignment to put \cmdname{mathstrut} in the argument.
+%
+% \section{Acknowledgments}
+%
+% The macro has been developed based on ideas of Stefano Di Gennaro
+% (Universit\`a dell'Aquila, Italy) and his student Andrea
+% Tonelli. Both have suffered from the earthquake of April~5, 2009: I
+% wish them, their families and their university a prompt recover.
