BESSELY
The BESSELY function returns the integer Bessel function Yn(x).
BESSELY(pos-x-value, n-value)
pos-x-value: A number value representing the x value at which you want to evaluate the function. pos-x-value must be greater than 0.
n-value: A number value representing the order of the function. n-value must be greater than or equal to 0. Any decimal portion is ignored.
Notes
This form of the Bessel function is also known as the Neumann function.
Examples |
|---|
=BESSELY(25, 3) returns 0.117924850396893. =BESSELY(25, 3.9) also returns 0.117924850396893, because any decimal portion of n-value is ignored. =BESSELY(-25, 3) returns an error, because negative values or 0 are not permitted. |
