Applets and Activities for Real Analysis

Lee Stemkoski (Adelphi Univ.) and Christopher Storm (Adelphi Univ.)

This suite of five interactive applets (written with GeoGebra) allows exploration of definitions and theorems commonly presented in first-year analysis courses. Topics include sequence convergence, continuity at a point, the Mean Value theorem, Taylor series, and Riemann sums. Included with each applet is a pair of activities: one for becoming comfortable using the applet, and one for using the applet to explore the associated topic in depth.

GeoGebra is an open source exploration/development tool that allows the creation of applets using a Java-based "player" understood by most browsers. If you have difficulty loading the applet, see for more information on the system/browser/java requirements for viewing GeoGebra applications.
