[Ipe-discuss] Fwd: How to draw a spring?

[Nathaniel Cunningham]

Yes, as Otfried said -- I plot multiple cycles of a parametric circle
(x=cos(t), y=sin(t) or similar) with an added translation (extra t term in
x or y).

I attach a screenshot showing an example including the values used in the
plot ipelet.
