**Playing with Multivariable Calculus with 3D Glasses**Presented by Paul Seeburger of Monroe Community College, Rochester, NY The multivariable calculus content has been developed with support from the National Science Foundation: NSF-DUE-CCLI #0736968**Project Main Goal:**The main goal of this project is to improve student understanding of the geometric nature of multivariable calculusconcepts, i.e., to help them develop accurate geometric intuition about multivariable calculus concepts and the various relationships among them.**Theprojectincludesfourparts:**• Creating a Multivariable Calculus Visualization applet using Java and publishing it on a website: web.monroecc.edu/calcNSF • Creating focused applets that demonstrate and explore particular 3D calculus concepts in a more dedicated way. • Developing guided exploration/assessments to be used by students to explore calculus concepts visually on their own. • Dissemination of these materials**Why use Visualization in Calculus?**• Calculus is the mathematics of change. Limits are defined in terms of change, Derivatives represent rates of change, and Definite Integrals represent total change in an antiderivative function. To see calculus clearly, we need to see motion and change occurring.**Why use Visualization in Calculus?**• Calculus is the mathematics of change.

To see calculus clearly, we need to see motion and change occurring. • Visualization helps make the geometric and motion-related connections become clearer and much easier to remember. It is especially when the concepts are in 3D.**Why use Visualization in Calculus?**• Calculus is the mathematics of change.

See two surfaces I printed below, a saddle and a knot.**Ways to use CalcPlot3D:**• Instructors can use them to visually demonstrate concepts and verify results during lectures. Also “What if…?” scenarios can be explored.**Ways to use CalcPlot3D:**• Instructors can use them to visually demonstrate concepts and verify results during lectures.

Look for my 2-hour workshop on using CalcPlot3D in teaching multivariable calculus, as well as creating these scripts at AMATYC 2011 in Austin!**Contact Info:**Paul Seeburger, Associate Professor of Mathematics at Monroe Community College Email: pseeburger@monroecc.edu NSF Project Website: http://web.monroecc.edu/calcNSF/
