EXCEL BESSELK FUNCTION
Excel BESSELK Function Introduction
The Excel Besselk function computes modified Bessel functions, Kn(x), commonly known as hyperbolic Bessel Functions. These are the Bessel functions evaluated using entirely fictitious arguments.
Description of Excel BESSELK Function
Syntax :
=BESSELK ( x, n )
Parameters :
x – The point at which the function will be evaluated.
n – A positive number indicating the modified Bessel function’s order.
(If the provided value of n is a decimal, Excel truncates it to an integer.)
Step By Step Guide of BESSELK Function
Example :
The order 1 modified Bessel function, K1, is seen in the graph above (x). If you wish to compute the value of this function at x = 0.05, use the Excel Besselk function as shown below:
=BESSELK(0.05, 1) yields the value 19.90967433.
Key Points
- #NUM!- Happens if either the provided value of x or the supplied value of n is 0.
- #VALUE!- This error occurs if any of the given parameters are not numeric.
