CalcTool

Drop me a line if you decide to use these at your institution and let me know how it's going. You may need to install a java run-time environment (jre). Click on the link above for more information.

CalcTool 1 is a suite of applets useful for teaching differential calculus. This suite is intended to provide the user with one collection of applets with a consistent interface that can be used to "discover", illustrate, or compute many important concepts. Functionality in this suite includes:

• The ability to graph, evaluate, and zoom in on functions.
• Illustration of function properties such as translation, scaling, and function composition.
• Illustration of various properties of trig functions.
• Illustration of the relationship between instantaneous and average rate of change.
• A visual representation of epsilon-delta proof of the limit of a function.
• The ability to compute symbolic derivatives.
• The ability to graph parametric functions
• The ability to graph vectors and illustrate vector addition.

Calctool 2 is a suite of applets useful for teaching integral calculus. This suite is intended to provide the user with one collection of applets with a consistent interface that can be used to "discover", illustrate, or compute many important concepts. Functionality in this suite includes:

• The ability to graph, evaluate, and zoom in on functions.
• The ability to compute symbolic derivatives.
• Illustration of Riemann sums using left/mid/right (and other) rules.
• Illustration of the Fundamental Theorem of Calculus.
• Graphs of Taylor series of functions.
• Graphs of power and function series.
• Slope fields and numerical solutios to differential equations.
• Visual illustration of Euler's method
