Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
-- Graphic object: parametric (<xfun>,<yfun>,<par>,<parmin>,<parmax>) -- Graphic object: parametric (<xfun>,<yfun>,<zfun>,<par>,<parmin>,<parmax>) Draws parametric functions in 2D and 3D.
This object is affected by the following graphic options: nticks, line_width, line_type, key, color and enhanced3d.

parametric (<xfun>,<yfun>,<par>,<parmin>,<parmax>) plots parametric function [<xfun>,<yfun>], with parameter <par> taking values from <parmin> to <parmax>.
Example:
(%i1) load(draw)$
(%i2) draw2d(explicit(exp(x),x,-1,3),
color = red,
key = "This is the parametric one!!",
parametric(2*cos(rrr),rrr^2,rrr,0,2*%pi))$3D
parametric (<xfun>,<yfun>,<zfun>,<par>,<parmin>,<parmax>) plots parametric curve [<xfun>,<yfun>,<zfun>], with parameter <par> taking values from <parmin> to <parmax>.
Example:
(%i1) load(draw)$
(%i2) draw3d(explicit(exp(sin(x)+cos(x^2)),x,-3,3,y,-3,3),
color = royalblue,
parametric(cos(5*u)^2,sin(7*u),u-2,u,0,2),
color = turquoise,
line_width = 2,
parametric(t^2,sin(t),2+t,t,0,2),
surface_hide = true,
title = "Surface & curves" )$ There are also some inexact matches for parametric. Try ?? parametric to see them.
