#### Parametric

-- 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`.

2D

`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.

```(%o1)                                true
(%i2) ```
