How to use BESSELJ Function in Excel

The BESSELJ function returns the Bessel function Jn(x).

Syntax: =BESSELJ(X, N)

The BESSELJ function syntax has the following arguments:

• x: required.  This is the value at which to evaluate the function
• n: also required.  This represents the order of the Bessel function.  If n is not an integer, it is truncated accordingly.

Example: Let’s look at some Excel BESSELJ function examples and explore how to use the BESSELJ function as a worksheet function in Microsoft Excel:

Syntax:  =BESSELJ(A2,B2)

Result:

Based on the Excel spreadsheet above, the following BESSELJ examples would return:

Note:

• If x is nonnumeric, BESSELJ returns the #VALUE! error value.
• If n is nonnumeric, BESSELJ returns the #VALUE! error value.
• If n < 0, BESSELJ returns the #NUM! error value.

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