# Reversed letters in a mathematical formula

Rotating a letter

For a work in logic, I need to write a iota upside down in a mathematical formula. I found this suggestion on the internet. First include [the usual math package] and the graphicx package

\usepackage{amsmath, amscd, amsthm, amssymb, mathrsfs,amsfonts}
\usepackage{graphicx}


in the preamble. Then use the command

\rotate{180}{$\iota$}


Indeed it works, but not perfectly: the axis of the rotation is at the basis of the letter (in 'normal' position). Hence, when I use this command, the reversed iota appears on a lower level than the text. I am thus not satisfied with this.

Does anyone have a better suggestion?

\rotatebox[origin=c]{180}{$\iota$}}


• The question is about rotating, not reflecting around the y-axis, which is what \reflectbox does. You can reflect around the x-axis with a combination of \scalebox and \raisebox, though. – egreg Sep 23 '16 at 22:56
