ParametricSpaceCurve is used for plotting parametric space curves in affine 3-space.
coordinate(c, i)
returns a coordinate function of c
using 1-based indexing according to i
. This indicates what the function for the coordinate component, i
, of the space curve is.
curve(c1, c2, c3)
creates a space curve from 3 component functions c1
, c2
, and c3
.
