ArcCos

ArcCos[z] gives the arc cosine of the complex number z.

Mathematical function (see Section A.3.10).

All results are given in radians.

For real z between and , the results are always in the range to .

ArcCos[z] has branch cut discontinuities in the complex z plane running from to and to .

See Section 1.1.3 and Section 3.2.6.
