Harmonic Numbers/Examples/H1

Example of Harmonic Number

$H_1 = 1$

where $H_1$ denotes the first harmonic number.

Proof

 $\displaystyle H_1$ $=$ $\displaystyle \sum_{k \mathop = 1}^1 \frac 1 k$ Definition of Harmonic Number $\displaystyle$ $=$ $\displaystyle \frac 1 1$ $\displaystyle$ $=$ $\displaystyle 1$
