ACOT functionThe ACOT function returns the inverse cotangent of a value in radians.
Parts of an ACOT function
ACOT(value)
Part
Description
Notes
value
The value for which to calculate the inverse cotangent.
Values must be a number.
Sample formulas
ACOT(0)
ACOT(-1)
ACOT(A1)
Notes
ACOT returns results that are between 0 and π (pi).
ACOT is sometimes written as “arccot” or “cot-1(x)” in mathematics or other programs.
Use the DEGREES function to convert the result of ACOT from radians to degrees.
