| Mar 25, 2011 at 10:53 | comment | added | Joshua P. Swanson | I noticed a very minor mistake: the $\psi(f(x)) = \pm 1$ should not have the $\pm$. I would ignore it if it weren't a convenient point for me to ask how to edit an answer. (The FAQ doesn't seem to be relevant and I don't see an "edit" button.) | |
