Definition
The series defined as:
- $\ds \sum_{n \mathop = 1}^\infty \frac 1 n = 1 + \frac 1 2 + \frac 1 3 + \frac 1 4 + \cdots$
is known as the harmonic series.
General Harmonic Series
Let $\sequence {x_n}$ be a sequence of numbers such that $\sequence {\size {x_n} }$ is a harmonic sequence.
Then the series defined as:
- $\ds \sum_{n \mathop = 1}^\infty x_n$
is a (general) harmonic series.
