# Series Grapher Applet

This applet displays the graph of a sum of the form "sum for k=N to M
of f(x,k)", where the lower and upper limits N and M are specifed by
sliders at the bottom of the applet. One of the terms in the series is
displayed in a separate graph. The term that is displayed is specified by a
third slider. The sample function is the series for sin(x). It would be nice if
the upper panel also displayed the function being approximated by the series. I
will add this later.

### Other examples to try

- exp: (x^k)/k!
- x*cos(x): (-1)^k *[ x^(2*k+1) ]/( 2*k )!
