This theorem requires a proof.
Exposition may be incorrect. Spiegel gives this in terms of the alternative form Euler and Bernoulli numbers.
You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by crafting such a proof.
Theorem
Let $n \in \Z_{>0}$ be a (strictly) positive integer.
Then:
| \(\ds B_{2 n}\) | \(=\) | \(\ds \frac {2n} {2^{2 n} \left({2^{2 n} - 1}\right)} \left({\sum_{k \mathop = 1}^n \dbinom {2 n - 1} {2 k - 1} E_{2 n - 2 k} }\right)\) | ||||||||||||
| \(\ds \) | \(=\) | \(\ds \frac {2n} {2^{2 n} \left({2^{2 n} - 1}\right)} \left({\binom {2 n - 1} 1 E_{2 n - 2} + \binom {2 n - 1} 3 E_{2 n - 4} + \binom {2 n - 1} 5 E_{2 n - 6} + \cdots + 1}\right)\) |
where:
- $B_n$ denotes the $n$th Bernoulli number
- $E_n$ denotes the $n$th Euler number.
