1A. Interactive Multivariable Calculus , Keith Stroyan, University of Iowa, Iowa City, IA: In this talk we will look at ongoing efforts to develop a combined print and electronic text for multivariable calculus, linked to many sources at appropriate points. See www.math.uiowa.edu/~stroyan/multicalc.htm Animation can make the visualization and motion inherent in 3-dimensional calculus more accessible to students. We will explore: building graphs from slice curves, direction of steepest ascent, zooming in on surfaces and contour graphs, the changing velocity and acceleration of a moving point, the flow of a vector field. Materials like these can help students master the traditional topics, but also make it possible for them to study more interesting, more varied, and deeper problems.
