In [1]: import Numeric as N

In [2]: N.arctan
N.arctan   N.arctan2  N.arctanh

In [2]: N.arctan ?
Type:           ufunc
String Form:    <ufunc 'arctan'>
Namespace:      Currently not defined in user session.
Docstring:
    arctan(x) returns array of elementwise inverse tangents.


In [3]: N.arctan2 ?
Type:           ufunc
String Form:    <ufunc 'arctan2'>
Namespace:      Currently not defined in user session.
Docstring:
    arctan2(x,y) is a safe and correct tan(x/y).

These are all Numeric ufuncs, so they operate on arrays
