ASINH

Description: Returns the inverse hyperbolic sine of a number. The inverse hyperbolic sine is the value whose hyperbolic sine is Number, so ASINH(SINH(Number)) equals Number.

Syntax: ASINH(Number)

• Number is any real number.

• 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:

• ASINH(-2.5) = -1.64723 [the inverse hyperbolic sine of -2.5]

• ASINH(10) = 2.998223 [the inverse hyperbolic sine of 10]
