Define additional math operators to be typeset in roman

\arccos, \arcsin, and \arctan seem to work, but not \arcsec, \arccot, \arccsc. I'm using the following math packages: amsmath,amssymb,amsthm.

    these aren't defined in amsmath, which is the applicable package. but they're easily enough cloned from the definition of one of the others as they appear in amsopn.sty. (amsopn.sty is loaded automatically by amsmath.) Commented Mar 15, 2012 at 17:50

You can define them yourself, with \DeclareMathOperator. See chapter 5 of amsmaths manual.

\( \arcsec \arccot \arccsc \)
