Hi,

been solving another volume problem here and though it seemed very straightforward, I'm getting very ugly integrals so it rather seems that I haven't chosen appropriate approach. I scanned how I did it, first in cartesian coordinates:

and then in spherical coordinates:

Neither of them seems useful...or maybe I'm substituting it wrongly.

Thank you for any advices.

**A**is the set the volume of which I'm trying to compute.Thank you for any advices.
