The following curve is given by \[ r(\theta) = a + b\cos(n\theta) \] for \(0 \leq \theta \leq 2\pi\) where \(a, b\) are constants and \(n\) is an integer. Change \(s\) to see how the curve progresses as \(\theta\) changes.

With the current technology, in order to use this demo, you need a CDF Player Plugin for your web browser. You can download it for free from Wolfram. Unfortunately, this cannot be run on any mobile devices. (I really want this, Wolfram.)
