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)
