While doing some quantum mechanics homework I came across 3 integrals that are giving me trouble.
1) dx/(a^2+x^2)^2 from negative infinity to infinity
2) (x^2 dx)/(a^2+x^2)^2 from negative infinity to infinity
3) (sinkx)^2/x^2 from 0 to infinity
I would appreciate any help that anyone has to offer. #3 resembles the Dirichlet Integral (if we drop off the squares) and then it would be pi/2. All k's and a's are just constants.
Thanks,
