Engineering - BESSELJ Function

Description

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

Syntax

BESSELJ(X, N)

Arguments

Notes

• 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 −

  $$J_n(x)=\sum_{k=0}^{\infty}\frac{(-1)^k}{K!\Gamma (n+K+1)}\left ( \frac{x}{2} \right )^{n+2k}$$

  Where −

  $$\Gamma (n+K+1)=\int_{0}^{\infty}e^{-n}x^{n+k}dx$$

Applicability

Excel 2007, Excel 2010, Excel 2013, Excel 2016
