An E-Learning Cycloid Curves Visualization.

Curve studied by Charles Bouvelles in 1501, Mersenne and Galileo in 1599, Roberval in 1634, Torricelli in 1644 etc...! This curve was not known by the Greeks. From the Greek kuklos: circle, wheel; name given by Galileo.

A cycloid is the curve traced by a point on the rim of a circular wheel as the wheel rolls along a straight line without slipping. A cycloid is a specific form of trochoid and is an example of a roulette, a curve generated by a curve rolling on another curve.
The cycloid has been called "The Helen of Geometers" as it caused frequent quarrels among 17th-century mathematicians.
