CYCLOÏDE À CENTRE
The notion of centred cycloid allows to regroup epi and hypocycloids.
Complex parametrization: for an epicycloid and for a hypocycloid ().
Pedal equation: with for an epicycloid and where a is the radius of the base circle, b the radius of the rolling one.

See also cycloidal curves, and the generalisation: the centred trochoids.
