the arithmetic progression, which does not contain 0. the harmonic mean is considered as a type of numerical average. the harmonic mean of the given number is the ratio of the number of observations to the sum of the reciprocal of the given numbers. the harmonic mean formula is given as:...
1.A positive integer n is called a harmonic number if the reciprocal sum of its divisors is an integer.如果一个正整数n的因数的倒数之和是一个正整数,我们称这个正整数n是一个调和数。 2.If the harnomic mean of all the divisors of n was an integer,then n was called a harmonic number.如...
most listeners will react with dissatisfaction: the music simply “stopped” instead of “ending” properly. A more satisfying ending is usually provided by giving clues in the music (in the progression of chords, for example, or the number and length of the phrases) that signal to...
