This demo displays the cycloid given by X(t) = (Rt – rsin(t), R – rcos(t)), along with rolling wheel which contains a point which traces
out the cycloid. To change any of the variables R, r, or t0,
use the following keys on the
appropriate line in the control window:
[<]: Decrease variable by one step.
[>]: Increase variable by one step.
[<<]: Decrease variable until it reaches its minimum value.
[>>]: Increase variable until it reaches its maximum
By default, the demo shows the point tracing out the curve, so that
only part of it is shown. To show the entire curve, check the box "Show
entire curve" by clicking on it.
