Examples of the Newton-Mercator Series
Newton-Mercator Series: $\ln 2$
The Newton-Mercator Series for $x = 1$ converges to the natural logarithm of $2$:
\(\ds \sum_{n \mathop = 1}^\infty \frac {\paren {-1}^\paren {n - 1} } n\) | \(=\) | \(\ds 1 - \frac 1 2 + \frac 1 3 - \frac 1 4 + \dotsb\) | ||||||||||||
\(\ds \) | \(=\) | \(\ds \ln 2\) |
This real number is known as Mercator's constant.
