IMCOSH

IMCOSH(inumber)

Returns the hyperbolic cosine of a complex number.

inumber

The complex number.

REMARKS

* If "inumber" is not in the form x + yi or x + yj, then #NUM! is returned.
* If "inumber" is not text, then #VALUE! is returned.
* You can use the COSH function to return the hyperbolic cosine of a number.
* You can use the COS function to return the cosine ratio of an angle.
* You can use the IMCOS function to return the cosine ratio of a complex number.
* You can use the COMPLEX function to convert real and imaginary coefficients into a complex number.
* You can use the IMSINH function to return the hyperbolic sine of a complex number.
* You can use the TEXT function to return the number as a formatted text string.
* This function was added in Excel 2013.
