# IMSECH

## Content

This function calculates the hyperbolic secant of specified complex number.

## Syntax

`IMSECH(complex_num)`

## Arguments

[Required] The *complex\_num* argument is a complex number to return the hyperbolic secant for.

## Remarks

An error is returned if the *complex\_num* argument is not in the form "x+yi" or "x+yj".

## Examples

`IMSECH("3+6i")` gives the result 0.09544
`IMSECH("7+2i")` gives the result -0.00075
