Abstract:

Finding the average speed for a trip, as well as problems in photography, music, electricity, and other areas, involve reciprocals. Students use algebraic and geometric techniques and reasoning to explore the basic properties of reciprocals and to investigate the relationship of the arithmetic and harmonic mean.
