Hey,(adsbygoogle = window.adsbygoogle || []).push({});

I was just going through my vector calc textbook for this year and everything was going well until I reached double and triple integrals. My problem is the whole symmetry thing; when does (forgive me, I can't figure out the symbols) the integral from a to b become twice the integral from 0 to a versus becoming zero?

Other than that, I think I was doing fine, but if you guys wouldn't mind posting some double and triple integral questions for me so I could get some practice that would be great.

Thanks,

Maurice
