Mathematicians, physicists, and engineers needed to quickly compute products long before computers conquered the world.

The \textit{slide rule} is an instrument that uses the logarithm to solve this problem. Before you continue, cut out and assemble your slide rule.
|
|

|
|
|
There are four scales on your slide rule, each labeled with a letter on the left side:
|
|
|
|
\def\sliderulewidth{13}
|
|
\begin{center}
|
|
\begin{tikzpicture}[scale=1]
|
|
\tscale{0}{9}{T}
|
|
\kscale{0}{8}{K}
|
|
\abscale{0}{7}{A}
|
|
|
|
\abscale{0}{5.5}{B}
|
|
\ciscale{0}{4.5}{CI}
|
|
\cdscale{0}{3.5}{C}
|
|
|
|
\cdscale{0}{2}{D}
|
|
\lscale{0}{1}{L}
|
|
\sscale{0}{0}{S}
|
|
\end{tikzpicture}
|
|
\end{center}
|
|
|
|
Each scale's ``generating function'' is on the right:
|
|
\begin{itemize}
|
|
\item T: $\tan$
|
|
\item K: $x^3$
|
|
\item A,B: $x^2$
|
|
\item CI: $\frac{1}{x}$
|
|
\item C, D: $x$
|
|
\item L: $\log_{10}(x)$
|
|
\item S: $\sin$
|
|
\end{itemize}
|
|
|
|
Once you understand the layout of your slide rule, move on to the next page.
