The applet illustrates many concepts associated with convergence and divergence of sequences and series, including the speed of convergence, subsequences, and Weyl's Theorem on Uniform Distribution. It provides a quick and easy illustration that finding limits of sequences by evaluating a few terms can be misleading. Similarly, as evaluating limits of functions by evaluating at a few points.
