Excel ATANH Function
The ATANH function calculates the inverse hyperbolic tangent of a number.
- number (required): The value for which you want to calculate the inverse hyperbolic tangent. Note: The number must be between -1 and 1.
The ATANH function returns a numeric value.
- The inverse hyperbolic tangent is the value whose hyperbolic tangent is number, so the result of =ATANH(TANH(number)) is number itself.
- ATANH returns the #NUM! error if number ≤ -1 or number ≥ 1.
- ATANH returns the #VALUE! error if number is not numeric.
To calculate the inverse hyperbolic tangent of the numbers listed in the table as shown below, please copy or enter the below formula in the top cell (D6) of the result list, and press Enter to get the result. Then select the result cell, and drag the fill handle (the small square in the lower-right corner of the selected cell) down to apply the formula to the below cells.
Instead of a cell reference, you can type the actual number value in the formula as shown below.
Excel ATAN Function
The ATAN function calculates the arctangent (inverse tangent) of a number, and returns an angle, in radians, in the range from -π/2 to π/2.
Excel ATAN2 Function
The ATAN2 function calculates the arctangent (inverse tangent) of the specified x- and y-coordinates, and returns an angle, in radians, in the range from -π/2 to π/2.
Excel CSCH Function
The CSCH function returns the hyperbolic cosecant of an angle specified in radians.
