The Analytic Physlet is a simple data source that evaluates a function at a predetermined number of points. These values can then be passed to other Physlets using a data connection. The data source is identified by the getID() method. It provides a data set containing the following variables to its data connection: x, y, and n.
If the analytic function is a function of time, the Physlet animation clock will cause the function to be evaluated at every clock tick.
