comment if $X\subseteq Y$, then $\bar{X} \subseteq \bar{Y}$
@MAS I believe Pedro is taking the definition of $\overline{X}$ to be "the smallest closed set containing $X$".

comment Convergence of the Power Series of $\log(1+\sin x)$
@square_one It could be that the author of the question intended you to "formally" expand the power series, which is a fancy term for "write the terms of the power series and ignore issues of convergence".
