Engineering - BESSELY Function

Description

The BESSELY function returns the Bessel function, Yn(x), (also known as the Weber function or the Neumann function), for a specified order and value of x.

Syntax

BESSELY(X, N)

Arguments

Argument	Description	Required/ Optional
X	The value at which to evaluate the function.	Required
N	The order of the function. If n is not an integer, it is truncated.	Required

Notes

If x is nonnumeric, BESSELY returns the #VALUE! Error value.
If n is nonnumeric, BESSELY returns the #VALUE! Error value.
If n < 0, BESSELY returns the #NUM! Error value.
The n-th order Bessel function of the variable x is −

$$Y_n(x)=\lim_{v \to n}\frac{J_v(x) \cos(v \pi) - J_{-v}(x)}{\sin(v \pi)}$$

Applicability

Excel 2007, Excel 2010, Excel 2013, Excel 2016
