Instructions:
Move sliders \(d\) (angular frequency of the Rhodonea curve), \(p\) (leg quantity) or \(\alpha\) (iteration angle) to change the graph. Press the "Start" button to watch the animation, this will move the \(p\) slider. Press the "Stop" button to interrupt the animation and press the "Reset" button to reboot the starting values. Click the "Rhodonea curve" box to show or hide the Rhodonea curve. Click the "Points" box to show or hide the points where the legs contact the Rhodonea curve.
$$ x = \cos \left(d t \right) \cos \left( t \right); \; y = \cos \left(d t \right) \sin \left(t \right) $$
