 animatecurve
 create an animation of the drawing of 2-D curves

 Calling Sequence animatecurve(F, r) animatecurve(P)

Parameters

 F - a single curve or a list or set of curves r - horizontal range P - a single curve in parametric form or a list or set of such curves

Options

 • numpoints : minimum number of points in final frame
 • paraminfo : parameter information in title

Description

 • The animatecurve command allows you to visualize the drawing of curves in 2-D space. The curve F can be specified as an expression in one variable or a procedure with one input parameter. For more information about the forms that F can take, see the plot and plot/function help pages.
 • Alternatively, the curve can be provided in parametric form, which is also described in the plot and plot/function help pages. Note that, if F or P is a set or list, it cannot have a combination of parametric and regular curves.
 • The second argument r is required for the first calling sequence only. It is not used for curves in parametric form. If F is a procedure or list/set of procedures, then r must be a range. Otherwise, r must have the form name=range where the left hand side is the variable name appearing in F.
 • the numpoints option sets the minimum number of points used in generating the curve for the final frame. This setting starts at a low number and increases gradually from the first frame to the last.
 • The paraminfo option shows the value of the parameter in the title. It works the same way as the paraminfo option in plots:-animate. However, it can take additionally a name or string to be used instead of the automatically generated name in the title.
 • Additional options, such as color or view, may be provided. Any of the options described in the plot/options help page that are applicable to curves may be used. Options accepted by the plots:-animate command, such as the frames option for specifying the number of animation frames, may also be given to the animatecurve command.
