I can do this problem if they give a general equation, but the infinite boundaries are confusing me.

I don't know how to inert all the symbols so I'll link you to the problem. It's problem number 105 in the packet. http://www.math.ufl.edu/%7Ehuang/calc3/fall2007.pdf [Broken]

If you can do the integral when a is finite, you will see the rest is trivial. The term which depends on a goes to zero. The last integral squared gives you the first integral when a becomes infinite.
