As in normal math, "atan" represents the arc tangent function:

Re: invers function

Mathcad's default unit for angle is radians.  You change units as you would any other expression by replacing the default with the unit of your choice.  (Since radians have no "real" units none shows for default.)  Mathcad allows "°" as a unit for degrees, I prefer "deg" but that's just personal preference.

That may be a personal preference,

international standards (ISO 80000-1) specifically state:
