Tan

  • Tan[ z ] gives the tangent of z.
  • Mathematical function (see Section A.3.10).
  • The argument of Tan is assumed to be in radians. (Multiply by Degree to convert from degrees.)
  • Sin[ z ]/Cos[ z ] is automatically converted to Tan[ z ]. TrigFactorList[ expr ] does decomposition.
  • See the Mathematica book: Section 1.1.3Section 3.2.6.
  • See also: ArcTan, Cot, TrigToExp, TrigExpand.
