Harmonic mean value
WebJun 7, 2024 · 1 Answer Sorted by: 3 Basically if a function is harmonic, then its value at a point is equal to the integral over a sphere of any radius (or its boundary) centred at that point. I.e. u ( x 0) = 1 n α ( n) r n − 1 ∫ ∂ B ( x 0, r) u ( x) d S ( x) WebHarmonic Mean formula and approach are quite different from other averages as the total number of observations or values are divided by the sum of the reciprocal of each observation or value in the set. It is one of the three classical Pythagorean means; the other two are AM and GM. Root Mean Square (RMS)
