ACOTH function
The ACOTH function returns the inverse hyperbolic cotangent of a value in radians.
Parts of an ACOTH function​
ACOTH(value)
| Part | Description | Notes |
|---|---|---|
value | The value for which to calculate the inverse hyperbolic cotangent. | * Values must not be a number between -1 and 1. |
Sample formulas​
ACOTH(2)
ACOTH(10)
ACOTH(A1)
Notes​
- If a number between -1 and 1 is passed to ACOTH, then the #NUM error is returned.
- ACOTH is sometimes written as "arccoth" or "coth^-1^(x)" in mathematics or other programs.
- Use the DEGREES function to convert the result of ACOTH from radians to degrees.
Examples​
| A | B | C | |
|---|---|---|---|
| 1 | Date | Formula | Result |
| 2 | 4 | =ACOTH(A2) | 0.2554128119 |
| 3 | -4 | =ACOTH(A3) | -0.2554128119 |
| 4 | =ACOTH(10) | 0.1003353477 |
