How to Use the BESSELK Function in Excel
This document provides a comprehensive guide on how to use the BESSELK function in both Microsoft Excel and Google Sheets.
Overview
The BESSELK function calculates the modified Bessel function of the second kind, Kn(x), for a specified order and a given value of x.
Syntax
The syntax for the BESSELK function is as follows:
BESSELK(x, n)x: The point at which the function is evaluated.n: The order of the Bessel function.
Examples
To clarify how the BESSELK function can be applied in Excel and Google Sheets, consider these examples:
Example 1: Calculating Bessel Function Value
Assume we need to compute the value of the modified Bessel function of the second kind, specifically K5(3).
| x | n | Result |
|---|---|---|
| 3 | 5 | =BESSELK(3, 5) |
Example 2: Using BESSELK in a Formula
Additionally, the BESSELK function can be incorporated into larger formulas. For instance, to calculate the sum of K0(2) and K1(3):
=BESSELK(2, 0) + BESSELK(3, 1)
Example 3: Using BESSELK in Data Analysis
In scenarios where column A consists of x values and column B contains n values, the BESSELK function can be used to calculate the Bessel function values for individual rows. For example:
| x | n | Result |
|---|---|---|
| 2 | 3 | =BESSELK(A2, B2) |
| 3 | 2 | =BESSELK(A3, B3) |
By utilizing the examples and syntax outlined in this guide, you will be equipped to effectively employ the BESSELK function in both Excel and Google Sheets for a variety of computational tasks involving the modified Bessel function of the second kind.
