# How to Use ACOT function in Google Sheets in 2020?

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.
