353- Exploring Conic Sections from Paper Folding to TI-NSpire™ Handheld Tools

Friday, April 15, 2011: 8:30 AM-10:00 AM
Marriott Ballroom 5 (Marriott Downtown)
Lead Speaker:
Arthur T. Mabbott

Participants will develop a deeper understanding of the definition of parabolas, ellipses, and hyperbolas by paper folding; discover that what looks like each conic section is really the "envelope" of tangent lines; find where the loci of points actually are; mimic the same actions on the TI-NSpire; and compare and contrast the ellipse with the hyperbola.
