Integration with Bessel function

  1. Nov 23, 2013 #1
    I would like to evaluate the following integral which has a Bessel function [itex]J_{3}(\lambda_{m}r)[/itex], and [itex]\alpha(r)[/itex] is a function.

    [tex]\int^{a}_{0} \alpha(r)rJ_{3}(\lambda_{m}r)dr[/tex]

    I'm unsure how to proceed due to the Bessel function. Am I supposed to use a recurrence relation? Which one?

    It depends on what the function α(r) is.

    The integral is part of a larger problem, which is to solve the wave equation in polar coordinates. The problem statement does not specify α(r).

    Should I just leave the integral as is?

    If this is homework, follow the homework template. We're not here to guess what you should or should no be doing.
