Syntax

IMCOSH(complex_num)

Arguments

The complex_num argument is a complex number to return the hyperbolic cosine for.

Remarks

An error is returned if the complex_num argument is not in the form "x+yi" or "x+yj".

Data Types

Accepts numeric and string data. Returns string data.

Examples

IMCOSH("8-3i") gives the result -1475.563
