Harmonic number

Summary

The harmonic numbers are the sums 1+1/2+⋯+1/n1 + 1/2 + \cdots + 1/n of the reciprocals of the first positive integers. They grow like the natural logarithm of nn. The node harmonic number gives the precise definition.

What this node needs for W2
  • edge instance_of in: at least two examples (0 of 2)
  • edge not_instance_of in: at least one non-example (0 of 1)
  • edge specializes both: the more general notions and the special cases (0 of 1)

The writing levels say how complete the text of a node is. They do not measure its truth.
