The di culties involved with evaluating in nite integrals involving products of Bessel functions are considered, and a method for evaluating these integrals is outlined. The method makes use of extrapolation on a sequence of partial sums, and requires rewriting the product of Bessel functions as the sum of two more well-behaved functions. Numerical. : Some Definite Integrals Involving Algebraic, Trigonometric and Bessel Functions. then we get (4) where Y. 0. is the Bessel function of the second kind, an d we used the addition theorem of Bessel functions[7]. The Integral I. 2 (k>k. 0) (5) In this case we use [7] (6) then we have (7) where. 3. F. 4 () is the generalized.

I need to do a definite integral involving a Bessel function but I cannot get it evaluated. I've already tried with eval() and subs() but the result is the same. This is only a part of a more complex situation related to radiated electric and magnetic fields I'm working on but a simplified version of the problem could be this code. D.2 BESSEL FUNCTIONS OF THE FIRST KIND The Bessel functions may be deﬁned in several different ways (as solutions of a differential equation, from generating functions, etc.), but let us express the Bessel functions as an inﬁnite series, as was done originally by Bernoulli and Fourier. If n is a nonnegative integer (0, 1, 2.

4 () is the generalized hypergeometric function [8]. The Integral I 2 (kintegrals involving algebraic, trigonometric and Bessel functions were presented. Similar integrals with higher orders of the Bessel functions can be evaluated using the same method. Highly oscillatory integrals, such as those involving Bessel functions, are best evaluated analytically as much as possible, as numerical errors can be di cult to control. We investigate inde nite integrals involving monomials in x multiplying one or two spherical Bessel functions of the rst kind j l(x) with integer order l.

These two integrals are classical results of integral involving Bessel functions. You may find methods in an very old but nice book, Chapter 13 "A treatise on the theory of Bessel functions" by Prof In particular, the first one is more complicated than. Formulas Involving Associated Legendre and Spherical Bessel Functions Associated Legendre Functions: d d˚ sin˚dg d˚ + m2 sin˚ g= 0.

However for the case that the oscillation is due to a Bessel function, there is no standard routine for calculating integrals of the form ;/ I, = f(x) J.(x) dx, (3) where n is an integer greater than or equal to zero.

The standard IMSL infinite integral routine dqdagl () performs quite poorly on integrals such as (3). We consider a new identity involving integrals and sums of Bessel functions. The identity provides new ways to evaluate integrals of products of two Bessel functions.

The identity is remarkably simple and powerful since the summand and the integrand are of exactly the same form and the sum converges to the integral relatively fast for most cases.
