Y= 1
Answer:
<h2>yes this is right and true</h2>
The first integral has a well-known beta function representation, so the second one should too. The beta function itself is defined as
and satisfies the identity
Later on, we'll also use the so-called reflection formula for the gamma function; for non-integer z,
as well as the identity
Replace in both integrals, so that
Now replace :
So, the original integral (which I condense here to a double integral) is
