 With variables, you can store strings or numbers. \textbf{Functions} allow
 you to manipulate these strings or numbers. Functions work like mathematical
 functions: They take some number of arguments in, and return one argument,
 usually a number or a string for our purposes. There are a lot of functions

 For now, let's just look at some simple examples.

 \begin{figure}
-\begin{lyxcode}
 \$a~=~-3.0;
 
 \$b~=~\&sin(\$a);
 
 \$c~=~\&pow(3.0,~\&abs(\$a));

 In the \textbf{Script} block, function names start with \textbf{\&}. Some
-example function calls are shown in figure \ref{Some Function Calls Figure}.
+example function calls are shown above.
 You can see that functions can take either variables, numbers, or the results
 of other function calls as parameters. The \texttt{\&sin} function returns
 the sine of an angle expressed in radians. \texttt{\&pow} raises the first
