=ACOT(number)
| Parameter | Deskripsi |
|---|---|
number |
The value of the cotangent of an angle. |
The Excel ACOT function returns the arc cotangent of a number. Given the input 1, the function returns 0.785398163 radians as the output.
=ACOT(1) // Returns 0.785398163 radians
The arc cotangent function is the inverse of the cotangent function, with a branch cut that maps to related angles.
=ACOT(COT(a)) // returns the angle or a branch cut angle
For example, the angle π/4 is mapped to π/4 with no branch cut.
=ACOT(COT(PI()/4)) // returns π/4
Where the angle -π/2 is mapped to positive π/2 with a branch cut.
=ACOT(COT(-PI()/2)) // returns positive π/2
