    arctan(x)

    Why doesnt math]\arctan(x)[/tex] yield a version that is not italicized, is it not a function, it says it is on LaTeX websites

    The same goes for any inverse trigonometric or hyperbolic functions

    i guess the syntax is off. \arctan x works ... \arctan x see?

    it is just the way the codes are set up. no parentheses

    [tex]\arctan(x)[/tex] produces:

    \arctan(x)

    Hmm...I think you are magic CaptainBlack, for it did not work before...well anyways

    \arctan(x)!....and thats happiness..not factorials xD

    \arctanh(x) \leftarrow what about arctanh?

    what were you doing?! you probably had a typo in the arctan itself

    arctanh is not on the standard list of functions so you have to do it the hardway:

    [tex]{\rm{arctanh}}(x)[/tex]

    {\rm{arctanh}}(x)
