The envelope of chords in a circle, the cardioid, the nephroid, and more line graphs
The envelope of chords in a circle, cardioid (k=2), nephroid (k=3) and other graphs from k = 1 to 129. This page shows 128 different chords patten in total.
Series: Envelopes of chords
Draw many chords using one simple rule, and a smooth curve appears. The circle comes first, followed by polygons.
The envelope of chords in a polygon
The envelope of chords in a circle has different pattern. By changing the circle to a polygon, we can have another version of envelope.
