Consider the double integral
[tex]
\int_{-\infty}^{\infty}dx f(x) \, \int_{-\infty}^{\infty}dy g(y)
[/tex]
The first one gives 0 the second one gives infinity (diverges). Then how to express the result of the integral? Is it 0 or infinity or neither (indeterminate)? Any other comments about the integration?
