The IMCOT function returns the cotangent of the given complex number. For example, a given complex number “x+yi” returns “cot(x+yi).”
Parts of an IMCOT function
IMCOT(number)
| Part | Description | Notes |
|---|---|---|
number | The complex number for which you want the cotangent. | This can be either the result of the COMPLEX function, a real number interpreted as a complex number with imaginary parts equal to 0, or a string in the format “x+yi” where x and y are numeric. |
Sample formulas
IMCOT(COMPLEX(4,6))
IMCOT(4)
IMCOT("2+3i")
Notes
The IMCOT function returns an error if the given number isn’t a valid complex number.
