BESSELY

Syntax:

BESSELY ( x , n )

Description: Weber's Bessel function Yn(x).

Mathematical Formula:

The n-th order Bessel function of the variable x is:

Arguments:

Name	Type	Description
x	number	The value at which to evaluate the function.
n	number	The order of the Bessel function. This value is truncated to an integer.

 

Return Type and Value: number – The Weber's Bessel function Yn(x).

However, if n < 0, #NUM! is returned.

[Example:

BESSELY(2.345,5) results in -4.98977884
