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
