All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, edu.davidson.tools.SDataSource, java.io.Serializable, edu.davidson.tools.SStepable

public class Analytic

extends SApplet

implements edu.davidson.tools.SDataSource, edu.davidson.tools.SStepable

The Analytic Physlet evaluates a function at a predetermined number of points. The range or the indexpendent variable can be set using the Min and Max embedding parameters. The number of points can be set with the NumPts embedding parameter.
