Animated Sequences
From the WWW Interactive Mathematics Server site -- see the author's paper spotlighted at the left. The objective of this mathlet is to investigate the behavior of series and sequences of functions. The input is a general term for a series or sequence of functions, and the output is an animation of the progression of the partial sums of the series or terms of the sequence.
Example
Plot of the series 
, where un = -(-1) nxn/n
Reference function: log(x + 1)
