A kind soul has pointed out my mismatched parentheses. Aaargh. It should read as follows: ----- Graphing the function f(x) = sgn(x) * |x|^(-1/(x-1)) over the domain (-1, 1) - {0} makes it appear quite smooth around x = 0. Question: Does this function have a power series that converges in some neighborhood of x=0 ? ----- As always: Sorry about that. —Dan -----
