ArcCos
ArcCos
[
z
]
gives the arc cosine
of the complex number
.
MORE INFORMATION
Mathematical function, suitable for both symbolic and numerical manipulation.
All results are given in radians.
For real
between
and
, the results are always in the range
to
.
For certain special arguments,
ArcCos
automatically evaluates to exact values.
ArcCos
can be evaluated to arbitrary numerical precision.
ArcCos
automatically threads over lists.
ArcCos
[
z
]
has branch cut discontinuities in the complex
plane running from
to
and
to
