One question on it was reverse the following integral and then evaluate it:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int_{0}^{\pi}\int_{x^2}^{\pi^2} x^3y dydx[/tex]

So I got the following reversed integral:

[tex]\int_{0}^{\pi^2}\int_{-\sqrt{y}}^{\sqrt{y}} x^3y dxdy[/tex]

When you first evaluate in respect to x you get 0, am I doing something wrong?
