Homework Help: Integral of Bessel function

  1. Aug 11, 2014 #1
    1. The problem statement, all variables and given/known data

    I've been given that the Bessel function

    ∫(J3/2(x)/x2)dx=1/2π (the integral goes from 0 to infinity).

    2. Relevant equations


    where a is a constant.

    3. The attempt at a solution

    Is the following correct?


    (This is just a part of a triple integral. We are not asked nor expected to bother too much with the Bessel function, since it is not the focus of the problem).

    No, I think one of the 'a's goes away. Do the substitution again: y = ax. With a>0.

    Oh, of course. I then get dx=dy/a, which solves the problem for me. Thanks!
