1. ### Integral Trouble

While doing some quantum mechanics homework I came accross 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...
