I am working my through the plotting chapter of the maxima reference manual (
http://maxima.sourceforge.net/docs/manual/en/maxima_8.html#SEC32 ) and I am
encountering a "Bad Range" error when I execute the plot2d function in discrete
mode.  An example maxima session that shows the error is included below.  Does
anyone have any thoughts on what I may be doing wrong?

Thanks in advance :-)

Bad Range 
FALSE must be of the form [variable,min,max]
 -- an error.  Quitting.  To debug this try DEBUGMODE(TRUE);
