Cycloid: Adjusting the Radius
Adjust the Equations
Recall, the equations for a cycloid from a circle with radius are:
Suppose we make our circle larger. For example, let . How do we need to adjust our equations?
The correct curve is shown in blue. Adjust the values for , , and to fix the pink curve to match.
Change the radius to using the slider. Adjust , , and again to make the curve match.
