Sec
  • Sec[ z ] gives the secant of z.
  • Mathematical function (see Section A.3.10).
  • The argument of Sec is assumed to be in radians. (Multiply by Degree to convert from degrees.)
  • .
  • 1/Cos[ z ] is automatically converted to Sec[ z ]. TrigFactorList[ expr ] does decomposition.
  • See the Mathematica book: Section 3.2.6.
  • See also: ArcSec, TrigToExp, TrigExpand.
