High school math students are expected to know about the arithmetic and geometric means, but the harmonic mean is studied—usually—"if there's time." This session will investigate the derivation of the harmonic mean formula and how it can be applied to the study of number, geometry, finance, and more (if there's time). Lots of problems on numerous handouts.
