# ACOT function

The 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.

## Examples

This example shows the inverse cotangent of numbers in radians:

 A B 1 Formula Result 2 =ACOT(4) 0.2449786631 3 =ACOT(-4) -0.2449786631 4 =ACOT(0) 1.570796327

This example shows the inverse cotangent of numbers converted to degrees:

 A B C 1 Data Formula Result 2 4 =DEGREES(ACOT(A2)) 14.03624347 3 -4 =DEGREES(ACOT(A3)) -14.03624347 4 0 =DEGREES(ACOT(A4)) 90
