Tanh

  • Tanh[ z ] gives the hyperbolic tangent of z.
  • Mathematical function (see Section A.3.10).
  • Sinh[ z ]/Cosh[ z ] is automatically converted to Tanh[ z ]. TrigFactorList[ expr ] does decomposition.
  • See the Mathematica book: Section 3.2.6.
  • See also: ArcTanh, Coth, TrigToExp, TrigExpand.
