Returns the inverse hyperbolic cotangent of the given number in radians.

**Sample Usage**

ACOTH(5)

ACOTH(C5)

**Syntax**

ACOTH(number)

- number - The number for which the inverse hyperbolic contangent is to be computed.

**Examples**

ACOTH(5) returns the inverse hyperbolic cotangent of 5 in radians.

ACOTH(C5) returns the inverse hyperbolic cotangent of the number contained in C5.

**Notes**

- Use the DEGREES function to convert the result of ACOTH into degrees. For example, DEGREES(ACOTH(5)).
- The number passed as an argument must not be between -1 and 1, inclusive.
