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
