111- Sinuosity, Crookedest Street in the World, Rivers, and y=sin x

Thursday, November 29, 2012: 3:30 PM-4:30 PM
Regency Ballroom A (Hyatt)
Lead Speaker:
Ron Lancaster

Lombard and Vermont Streets in San Francisco are two of the most crooked streets in the U.S. We will use Sketchpad and Nspire CAS to explore sinuosity, a ratio used to measure the crookedness of these streets, of rivers, and of y = sin x. Connections to mathematical topics will include trigonometry, circles, distance between two points, and arc length.
