Just a question of notation here, my lecturer will wright an integral like this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int_3^6 dx \int_{-\sqrt{4-x^2}}^{\sqrt{4-x^2}}y \, dy[/tex]

But mean this:

[tex]\int_3^6 \int_{-\sqrt{4-x^2}}^{\sqrt{4-x^2}}y \, dy \, dx[/tex]

Is this standard notation? It seems rather odd to me.
