Is the cotan function defined somewhere? I cannot find it. It is defined as cotan(x)=cos(x)/sin(x). Should it be \newcommand{\cotan}{\mathrm{cotan}}? I'm suspecting somewhere a declareoperator command or something.

For a function to calculate cotan=cos/sin, \usepackage{fp}... ;-) – Bruno Le Floch Apr 9 '11 at 12:11

Easier to use \DeclareMathOparator, see tex.stackexchange.com/questions/671/… – Caramdir Apr 9 '11 at 3:03
NB: you can use backticks ` to mark your inline code and if you indent lines by 4 spaces, then they are marked as a code sample. You can also highlight the code and click the "code" button (with "101010" on it). – Caramdir Apr 9 '11 at 3:16
