Query: The connection between the Basel problem and a special integral   By using Fubini theorem or Tonelli theorem, we find that the zeta function
value at 2 is equal to a special integral. Furthermore, We find that this
special integral is two times of another special integral. By using this fact
we obtain the relationship between Genocchi numbers and Bernoulli numbers. And
get some results about Bernoulli polynomials.
