comment Which is true for a sequence $(x_n)$ such that $x_n\in (o,\frac{1}{n})$?
@Flip The key point is the sentence “it has a continuous extension to [0,1]”. Do you understand it?

@Flip - $x_n$ is convergent in $[0,1]$. Mustafa's answer is perfectly right.

comment What algorithm is used by computers to calculate logarithms?
@robjohn The main interest of Pade-Hermite approximant (computed for example from a continued fraction expansion) is that the convergence is much faster than Taylor series on the whole complex plane (not just the unit disk).
