Integration of dirac delta composed of function of integration variable
Yes, you are right about the units. And someone else aside from myself got phsopher's result as well. A few equations back, the author defines the probability distribution that he is using, and if I integrate over all angles and radial distances, I don't get unity. I think there are...- kmdouglass

Integration of dirac delta composed of function of integration variable
Hi all, I'm working through Chandrasekhar's http://prola.aps.org/abstract/RMP/v15/i1/p1_1" and can not understand the steps to progress through Eq. (66) in Chapter 1. The integral is: \prod^{N}_{j=1} \frac{1}{l^{3}_{j}|\rho|}\int^{\infty}_{0} sin(|\rho|r_{j})r_{j}\delta...- kmdouglass
