                      2: 
                      3: The \textbf{function} tag allows you to specify the curve to be 
                      4: plotted as a formula, instead of numerical data.
                      5: 
1.2     ! matthew     6: The function must be a mathematical expression.
1.1       matthew     7: Use the independent variable ``x'' for cartesian plots and ``t'' for polar 
                      8: plots.
                      9: Implicit multiplication is not accepted by Gnuplot.
                     10: The following are examples of valid functions and invalid functions:
                     11: 
                     12: \begin{itemize}
                     13: \item \texttt{sin(x)}
                     14: \item \texttt{sin(2*x)}
                     15: \item \texttt{sin(x**2)}
                     16: \item \texttt{exp(x)}
                     17: \item \texttt{3*x**x}
                     18: \item \texttt{exp(sin(2*x))}
                     19: \item \texttt{sinh(x)}
1.2     ! matthew    20: \item \texttt{sin(t)*cos(t)} (\textit{polar plot only})
