We use a trick to let the trace "open up" as you drag a point.
The trick is this: an initial point is given parametric location s*t, create a tangent at this point and its envelope as s varies.
Now hide the original point and create another point with parameter t, and make it draggable.
Dragging the new point changes the value of t and we see a trace from 0 to t.
There isn't much difference between a catenary and its approximate parabola.
The catenary is the correct model of an ideal chain.
But the parabola fits fairly well too.
The polar point of a line in a parabola is a common point to the chords defined by the common tangents through the points on the line.
