Refer to Problems 1, 2, and 3. Show that the harmonic mean of a and b equals the geometric mean squared divided by the arithmetic mean.
Problems 1
Arithmetic Mean If a < b, show that The number
is called the arithmetic mean of a and b.
Problems 2
Geometric Mean If 0 < a < b, show that The number is called the geometric mean of a and b.
Problems 3
Harmonic Mean For 0<a < b, let h be defined by
Show that a < h < b. The number h is called the harmonic mean of a and b.
