The median increases less than the mean increases.
Take

so that you have

which gives a Jacobian determinant of

So upon transforming the coordinates to the u-v plane, you have (and I'm guessing on what the integrand actually is)

A perfect square is a number that can be expressed as the product of two equal integers. To determine that a trinomial is a perfect square we use the the discriminant given by:
b^2-4ac
where a,b and c have been obtained from the trinomial given by:
ax^2+bx+c;
if the value of the discriminant is a perfect square then the trinomial is a perfect square trinomial
