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 .
  • See the Mathematica book: Section 3.2.6.
