Excel Tutorial – BESSELI

The BESSELI function in Microsoft Excel is a math and trigonometry function that calculates the modified Bessel function of the first kind. It takes two arguments: the number for which you want to calculate the Bessel function, and the order of the function.

Here’s a step-by-step guide on how to use the BESSELI function:

1. Open your Microsoft Excel spreadsheet and select the cell where you want to display the result.
2. Type the following formula into the selected cell: =BESSELI(x, n)
3. Replace “x” with the number for which you want to calculate the Bessel function.
4. Replace “n” with the order of the Bessel function. The order must be a non-negative integer.

For example, if you want to calculate the Bessel function of order 0 for the number 1, the formula would be: =BESSELI(1, 0)

5. Press Enter to complete the formula and display the result.

Note: The Bessel function is a mathematical function that arises in solutions to differential equations and has applications in fields such as physics, engineering, and economics. However, it is not a commonly used function in Excel, as it is mostly used by advanced users and specialists in these fields.
