How to Use the LN Function in Excel
The LN function in Excel and Google Sheets is designed to compute the natural logarithm of a number. The natural logarithm uses ‘e’ (approximately 2.71828) as its base.
Syntax
The syntax for the LN function is identical in both Excel and Google Sheets:
=LN(number)Examples
Here are some examples to illustrate the use of the LN function.
Example 1: LN in Excel
Consider calculating the natural logarithm of the number 10 in Excel.
| Formula | Result |
|---|---|
=LN(10) |
2.302585093 |
The result, approximately 2.302585093, is the natural logarithm of 10.
Example 2: LN in Google Sheets
Next, let’s compute the natural logarithm of the number 5 in Google Sheets.
| Formula | Result |
|---|---|
=LN(5) |
1.609437912 |
The result, approximately 1.609437912, represents the natural logarithm of 5.
Use Cases
- Financial modeling
- Population growth calculations
- Analyzing exponential trends
- Calculating half-life in chemistry
The LN function is versatile, useful for a range of applications including financial modeling, population studies, trend analysis in data sets, and scientific calculations such as decay rates in chemistry.
In conclusion, the LN function serves as an essential tool in Excel and Google Sheets, facilitating effective handling of operations that involve natural logarithms and exponential models.
