BESSELY

Returns the Bessel function, which is also called the Weber function or the Neumann function.

Syntax

BESSELY(x,n)

X is the value at which to evaluate the function.

N is the order of the function. If n is not an integer, it is truncated.

Remarks

• 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:
