-- Push "Derive" to differentiate once.
-- Hit "2nd&Up Diff" to find the second derivative. Hit again to find the higher
-- "Plot" opens a new application with F(x), F'(x), and F"(x) graphed
altogether. The graph can be inaccurate when dealing with discontinuous
function, but it is always possible to adjust extremes and replot.
-- This Applet uses the Derive class written by Patrik Lundin that is available in the following site:
