GeoGebra
Doug Kuhlmann, Grainger
GeoGebra is dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. On the one hand, GeoGebra is an interactive geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. If you have only thought of GeoGebra as a free version of Sketchpad, come see what it can do for your precalculus and calculus classes. Only time offered
Crop Circles - the Mathematics of Central Pivot Irrigation
Phil Todd, Forum
When farmers use central pivot irrigation, they create circular fields, and leave some land uncultivated. They tend to want to maximize the amount of cultivated land. Preexisting geographic features (roads, property boundaries, rivers etc.) along with a technical requirement not to overlap fields add interest and variety to the basic problem. The results of their efforts will be viewed using Google Earth, analyzed using Geometry Expressions and CAS, and related to classical solved and unsolved mathematical problems. In the process we will see an economically compelling application of Euclidean geometry. Only time offered

A Geometrical Description of Telescope Aberration
Philip Todd, Forum
Light parallel to the axis of a parabolic mirror reflects through the focus of the parabola. What happens to light rays coming in at an angle to the axis? If the angle is small enough, they do "focus" to a region, but not to a point. Can we come up with a measurement of the breadth of this focus region, which would characterize the aberration away from the central axis of a telescope? This problem was posed last summer to a high school student, armed with Geometry Expressions and Maple. He came up with an elegant geometrical solution. We will describe his solution, the path he took to arrive at it, and the further extensions he made. Only time offered

Learn Trig Identities from Complex Arithmetic (and the binomial theorem)
Doug Kuhlmann, Grainger
We usually teach the polar form of complex multiplication via trig identities. Learn how to reverse the process and derive trig identities by first proving the polar form of complex multiplication without trig. Using this and the binomial theorem we can easily derive identities for sin(3x), cos(4x) or tan(5x). We can also quickly derive the power reduction formulas for cos^4(x) or sin^6(x) . You can also use complex multiplication to easily show, for example, that arctan(1)+arctan(2)+arctan(3)=p. Only time offered
