569- Finding a Triangle's Area: A Case Study in Vertical Articulation

Friday, April 19, 2013: 3:30 PM-4:30 PM
Mile High 4 E/F (Convention Center)
Lead Speaker:
Margaret Coffey

The task of finding the area of a triangle occupies students from elementary grades through calculus. Join me on a "vertically articulated" tour: from counting squares to square matrices, from geometry to trigonometry, to the cross product of two vectors. Historical highlights of the tour are the contributions of Heron and Georg Pick.
