W : Build on studentsâ knowledge of literary elements by explaining how to draw conclusions, including determining the theme, based on information in folklore. H : Engage students by using the story Goldilocks and the Three Bears to model how to draw conclusions based on text.
For a signal whose fundamental frequency is f, the second harmonic has a frequency 2 f, the third harmonic has a frequency of 3 f, and so on. Let w represent the wavelength of the signal or wave in a specified medium. The second harmonic has a wavelength of w /2, the third harmonic has a wavelength of w /3, and so on.
From the third formula in the above equation, it is more apparent that the harmonic mean is related to the arithmetic and geometric means.Equivalently, the harmonic mean is the reciprocal of the arithmetic mean of the reciprocals.As a simple example, the harmonic mean of 1, 2, and 4 is.The Harmonic mean is a Schur-concave function, and dominated by the minimum of its arguments, in the sense that for any positive set of arguments, Thus, the harmonic mean can not be made arbitrarily large by adding more big values to the argument set.he harmonic mean is related to the other Pythagorean means, as seen in the third formula in the above equation. This is noticed if we interpret the denominator to be the arithmetic mean of the product of numbers n times but each time we omit the j th term.
