Unsigned Stirling Number of the First Kind of n+1 with 0

Theorem
Let $n \in \Z_{\ge 0}$.

Then:
 * $\ds {n + 1 \brack 0} = 0$

where $\ds {n + 1 \brack 0}$ denotes an unsigned Stirling number of the first kind.

Proof
We are given that $k = 0$.

So by definition of unsigned Stirling number of the first kind:
 * $\ds {n \brack k} = \delta_{n k}$

where $\delta_{n k}$ is the Kronecker delta.

Thus:

Hence the result.
