ArcSec

ArcSec[z] gives the arc secant of the complex number z.

Mathematical function (see Section A.3.10).

All results are given in radians.

For real z outside the interval to , the results are always in the range to , excluding .

ArcSec[z] has a branch cut discontinuity in the complex z plane running from to .
