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. |
|
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 |
