# IMCOSH

The `IMCOSH` function returns the hyperbolic cosecant of a complex number in rectangular notation.

## Usage

Use the `IMCOSH` formula with the syntax shown below, it has 1 required parameter:

Parameters:
1. number (required):
The complex number for which to calculate the hyperbolic cosecant. The number can be provided as a real or imaginary number, or in x + yi or x + yj format.

## Examples

Here are a few example use cases that explain how to use the `IMCOSH` formula in Google Sheets.

### Calculate hyperbolic cosecant of a complex number

This function can be used to calculate the hyperbolic cosecant of a complex number in rectangular notation.

### Perform engineering calculations

The `IMCOSH` function is part of the Engineering category of functions in Google Sheets and can be used to perform various engineering calculations.

## Common Mistakes

`IMCOSH` not working? Here are some common mistakes people make when using the `IMCOSH` Google Sheets Formula:

### Using the Wrong Input Format

One common mistake when using the `IMCOSH` formula is providing an input in the wrong format. The input must be a complex number in the form of a + bi.

### Confusing Hyperbolic Cosine with Other Functions

Another common mistake is confusing the `IMCOSH` function with other trigonometric or hyperbolic functions.

The following functions are similar to `IMCOSH` or are often used with it in a formula:

• `IMSINH`

The IMSINH function calculates the inverse hyperbolic sine of a given complex number. Inverse hyperbolic sine of a complex number is the value whose hyperbolic sine is the given complex number. This function is useful in engineering applications that involve complex numbers.

• `IMTAN`

Calculates the inverse of the tangent of a number in radians. The resulting angle is returned in radians. This function is most commonly used in engineering calculations that involve angular measurements.
