# IMLN

The `IMLN` function returns the natural logarithm of a complex number. It takes one required parameter, `complex_value`, which is the complex number for which to calculate the natural logarithm.

## Usage

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

Parameters:
1. complex_value (required):
The complex number for which to calculate the natural logarithm.

## Examples

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

### Calculate the natural logarithm of a complex number

The `IMLN` function can be used to find the natural logarithm of a complex number, which is useful in a variety of mathematical applications.

### Perform complex number operations

The `IMLN` function is often used in combination with other complex number functions, such as `IMAGINARY` and `REAL`, to perform complex number operations.

### Convert between polar and rectangular coordinates

The `IMLN` function can be used in conjunction with other complex number functions to convert between polar and rectangular coordinates.

## Common Mistakes

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

### Incorrect number of arguments

The IMLN formula requires one argument, which is the complex value. Make sure you are not providing too many or too few arguments.

### Invalid input value

The IMLN formula can only accept complex numbers as input. Check that the input value is in the correct format and does not contain any non-numeric characters.

### Incorrect format of output

The output of the IMLN formula is in the form of a complex number. If the output is not in this format, check that the input value is valid and that the formula is written correctly.

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

• `IMAGINARY`

The `IMAGINARY` function in Google Sheets returns the imaginary coefficient of a given complex number. The imaginary coefficient is the part of the complex number that is multiplied by the imaginary unit. This function is often used in engineering and scientific applications that involve complex numbers.

• `IMABS`

The `IMABS` function returns the absolute value (modulus) of a complex number. This is useful when working with complex numbers in engineering or scientific calculations.

• `IMARGUMENT`

The `IMARGUMENT` function returns the argument corresponding to the given number in a complex number in rectangular form.

• `IMCONJUGATE`

The `IMCONJUGATE` formula returns the complex conjugate of a given complex number. This formula is commonly used in engineering and physics calculations involving complex numbers.
