Arg
Arg
[
z
]
gives the argument of the complex number
.
MORE INFORMATION
Mathematical function, suitable for both symbolic and numerical manipulation.
Arg
[
z
]
is left unevaluated if
is not a numeric quantity.
Arg
[
z
]
gives the phase angle of
in radians.
The result from
Arg
[
z
]
is always between
and
.
Arg
[
z
]
has a branch cut discontinuity in the complex
plane running from
to 0.
Arg
[0]
gives 0.
Arg
automatically threads over lists.
