TANH

Description: Returns the hyperbolic tangent of a number.

Syntax: TANH(Number)

• Number is any real number.

Remarks:

• The formula for the hyperbolic tangent is:

• When used in an event analysis flowchart, Number must evaluate to a numerical value. It can include:

• Numerical values

• Standard operands (+, -, *, /)

• Predefined mathematical functions (exp, log, sin, etc.)

• Event analysis internal functions

• Event analysis resources

• References to any ReliaSoft Workbooks

Example:

• TANH(0.5) = 0.462117 [the hyperbolic tangent of 0.5]
