JavaSketchpad Calculus Applets consists of six applets, the Geometer’s Sketchpad constructions that generate the applets, online student activities to accompany the applets, and explanations of how the applets were written.  The applets illustrate features that are new to JSP4, features available to JSP but not GSP, and work-arounds to accomplish constructions, such as graphs of functions, that are supported by GSP but not directly available in JSP.
