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 www.geogebra.org for more information on the system/browser/java requirements for viewing GeoGebra applications.
