# SINH()

Hyperbolic Tangent of the argument

Syntax

  TANH (nArea) -> nHyperbolicTangent

Arguments

  <nArea> the size of the area (see below)

Returns

  <nHyperbolicTangent> the hyperbolic tangent of <nArea>

Description

  The function TANH() calculates the hyperbolic tangent of the argument. In analytical mathematics it is defined as SINH(x)/COSH(x).

Examples

          ? tanh (0.0) --> 0.0
          ? tanh (1.0) --> 0.7615...
    Tests
          tanh (0.0) == 0.0
          tanh (-0.5) == -tanh(0.5)
