The ATANH function returns the hyperbolic arctangent of a number.
This function can be useful in mathematical and engineering calculations where hyperbolic functions are required.
Syntax
ATANH(value)
Argument |
Description |
Permitted values |
|---|---|---|
value |
Number for which the hyperbolic arctangent is calculated |
Any real number in the range from −1 to 1 (excluding the limits) or a reference to a cell with a number |
Examples of use
Calculation of hyperbolic arctangent for 0:
=ATANH(0)
Result: 0.
Calculation for 0.5:
=ATANH(0.5)
Result: approximately 0.5493.
Attempt to calculate for a value out of range (−1, 1):
=ATANH(2)
returns the #NUM! error since the value is out of the allowed range.
Notes
–The return value is in radians.
–To convert the result to degrees, use the DEGREES function: =DEGREES(ATANH(value))
