IMCOTH function

The IMCOTH function returns the hyperbolic cotangent of the given complex number. For example, a given complex number "x+yi" returns "coth(x+yi)."

Parts of an IMCOTH function

IMCOTH(number)

 Part Description Notes number The complex number for which you want the hyperbolic 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

IMCOTH(COMPLEX(4,6))

IMCOTH(4)

IMCOTH("2+3i")

Notes

The IMCOTH function returns an error if the given number isn't a valid complex number.
