Just for fun. For some constant number , consider the function . Let be the set of all pairs so that and is a limit of a subsequence of the sequence , , , .... Write a computer program to draw the set in the plane whose axes are and , and if your program and picture are nice, they'll find their place on this class' web site.
It's a hard one, but it's well worth it. The set is way more complex than you would expect, with parts that scream ``structure'' and parts that scream ``mess''. If you've ever heard the word ``chaos'' in a mathematical context before, this is it. And if you've ever seen pictures of the beautiful ``Mandelbrot Set'', our is a close relation.
