 RationalFunctionPlot
 plot rational functions

 Calling Sequence RationalFunctionPlot(f, opts)

Parameters

 f - rational function (ratio of polynomials) in at most one variable opts - (optional) equation(s) of the form option = value where option is one functionoptions, showslantasymptotes, showverticalasymptotes, showremovables, slantasymptoteoptions, verticalasymptoteoptions, removableoptions; specify output options

Description

 • The RationalFunctionPlot(f) command plots a rational function.  If f has any asymptotes, they are also displayed.
 • The optional parameters opts specify the desired options for the resulting plot.  The available options are:
 functionoptions = list
 Specifies the plot options for f.
 showslantasymptotes = true/false
 Specifies whether or not to show the slant asymptotes of f.
 showverticalasymptotes = true/false
 Specifies whether or not to show the vertical asymptotes of f.
 showremovables = true/false
 Specifies whether or not to show the removable discontinuities of f.
 slantasymptoteoptions = list
 Specifies the plot options for the slant asymptotes (including horizontal) of f.
 verticalasymptoteoptions = list
 Specifies the plot options for the vertical asymptotes for f.
 removableoptions = list
 Specifies the plot options for the removable discontinuities for f.
 caption = anything
 A caption for the plot.
 The default caption is constructed from the parameters and the command options. caption = "" disables the default caption. For more information about specifying a caption, see plot/typesetting.
 • For information on including additional plot option(s), see the plot help page.
 • For information on how to change the default colors, see the Student [SetColors] help page.
