IMCOSH function

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.
