Plz, help to integrate this:
[tex] /int_{-/infinity}^{+/infinity}dk /frac{exp(ikx)}{k^2+a^2}[ /tex ]
[tex] /int_{-/infinity}^{+/infinity}dk /frac{exp(ikx)}{k^2+a^2}[ /tex ]
What I think is that it is a divergent integral. But it is given in the book. So, maybe it has any physical meaning ?!(1) Ask homework questions in the homework forum.
(2) This is a help forum, not an answer forum. You need to indicate what you've already tried, or what thoughts you've had on the problem.
I just answered a similar question yesterday. Here's the answer: "Set up a contour integral and use the residue theorem." It's not divergent.What I think is that it is a divergent integral. But it is given in the book. So, maybe it has any physical meaning ?!
