ACOTH functionThe 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.
