Why Are Shot Puts Thrown at 31[degrees]? Using Autograph for Applications of the Parabola
Butler, Douglas
Mathematics Teacher, v103 n9 p689-692 May 2010
Autograph is a two- and three-dimensional dynamic statistics and graphing utility, developed in England, that has grown out of direct classroom experience. A simple select-and-right-click interface, together with tools such as Autograph's unique Slow Plot, Scribble Tool, and dynamic Constant Controller help make the classroom experience interactive. Autograph can be used to introduce most students to their first nonlinear function. To their surprise, they will discover that parabolas are everywhere. In this article, the author illustrates applications and solutions in finding the angle of elevation for games like shot-put and javelin toss using Autograph. (Contains 12 figures.)
