1. The problem statement, all variables and given/known data I need to show that the definite integral (from 0 to infinity) of the Bessel function of the first kind (i.e.Jo(x)) goes to 1. 2. Relevant equations All of the equations which I was given to do this problem are shown in the picture I have attached. However, I believe the result shown in part (b) is most relevant. 3. The attempt at a solution I have fully worked through parts (a) and (b) of this question; however, I am unsure about how to attack this last problem. I was wondering if Parseval's theorem may be useful here but that has been my most recent thoughts on it. Any help would be greatly appreciated.
