Given [tex]\frac{1}{| \int\ f(\ x)\ g(\ x)\ d\ x\ |}=\int \frac{\ f(\ x)}{\ g(\ x)}\ d\ x[/tex]

Does the above put any condition on f(x) and g(x)?

2. Relevant equations

3. The attempt at a solution

The | | in the denominator reminds me of Darboux inequality...In fact it looks impossible to solve analytically...Can it be solved numerically?
