Why not use polar coordinatesHi there. I have this problem with double integral, which says: calculate using a double integral the volume limited by the given surfaces: ,
Its a cylinder cut by a plane.
At first I've did this integral:
The thing is that when I solve this the terms null themselves and it gives zero. There is evidently something that I'm doing wrong, I've realized that I'm taking off a half of the volume to the other, so I think I'm defining one part of the area over which I'm making the integral as negative. Is this true? And the thing is: How do I solve this properly? I've introduced this double integral into mathematica and it solved it and gave . So, its clear I'm doing something wrong
I also thought on trying other way:
But it gets more complicated that way.
Bye there, and thanks for helping.
