E47 -- Inventio summae cuiusque seriei ex dato termino generali
(Finding the sum of any series from a given general term)
Euler continues with the methods of E25 to attack
z(2) for a second time. He starts with a Taylor series, builds a
"Bernoulli polynomial" and uses it to evaluate 0n + 1n + 2n +
3n + ... +
(x - 1)n, (x=1, 2, 3, ...) and gets the relationship on Bernoulli numbers that
(B+1)n+1 - Bn+1 = 0.
He gets an infinite series approximation for the nth partial sum of the harmonic series.
According to the records, it was presented to the St. Petersburg Academy on October 13, 1735.
