The IMCOSH function returns the hyperbolic cosine of the given complex number. For example, a given complex number “x+yi” returns “cosh(x+yi).”
Parts of an IMCOSH formula
IMCOSH(number)
Part | Description | Notes |
---|---|---|
number | The complex number for which you want the hyperbolic cosine. | 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
IMCOSH(COMPLEX(4, 6))
IMCOSH(4)
IMCOSH("2+3i")
Notes
The IMCOSH
function returns an error if the given number isn’t a valid complex number.
