Thanks to both of you, that helps quite a bit. I see where I went wrong with coming up with zero. The signs were messing me up. So now I'm on to my next stumbling block, and I'm quite certain I'm just being dense. Is \rho=\sqrt{20}? Something tells me I don't have that right. I'll...

Okay, I've just gotten back to this problem and I'm now even more confused. Here it is, step by step: \int_{0}^{2\pi}\int_{0}^{\pi}\int_{0}^{\sqrt{20}} \rho^2 sin\phi d\rho d\phi d\theta \int_{0}^{2\pi}\int_{0}^{\pi} \rho^3/3 sin\phi d\phi d\theta = \int_{0}^{2\pi}\int_{0}^{\pi}...

Thanks. I knew it wasn't simply d\rho d\phi d\theta, I just didn't know the equation was \rho^2 sin\phi. How do you get that? I'd really like to understand the entire method so that I can apply it to more than just this problem. How is \phi = 0 to \pi? I don't know how to get there...

I know this has been answered in another thread, but it still isn't entirely clear to me. This particular section in class is giving me some major problems and I'm hoping someone can shed some light on things. This is probably one of the easier problems in this assignment and I'm hoping if I...
