The Axial Curve Rotator.
Hunter, Walter M.
This document contains detailed directions for constructing a device that mechanically produces the three-dimensional shape resulting from the rotation of any algebraic line or curve around either axis on the coordinate plant. The device was developed in response to student difficulty in visualizing, and thus grasping the mathematical principles associated with curve rotation around the x- or y-axis. In addition to the directions, the document also includes a discussion of the development of prerequisite concepts, a lesson description, photographs of the axial curve rotator, and real world applications of the teaching unit.
