The question asks: "Let $D$ denote the set in $\mathbb{R^3}$ lying above the cone $z=\sqrt{x^2+y^2}$ and inside the sphere $x^2+y^2+z^2=4$. Set up the following integrals over $D$ as iterated integrals in spherical coordinates. You should think about which ones you can evaluate." would this be correct?: $$\int_0^\pi \int_0^\frac{\pi}{4} \int_0^2 (\rho^2)\rho^2\sin(\phi)d\rho d\phi d\Theta$$ comment: sorry, this is for part a.AnonymousThu, 24 Jul 2014 09:57:59 -0500http://calc3.askbot.com/question/159/http://calc3.askbot.com/question/158/in-class-problem/I am having trouble understanding #4e from todays worksheet: "Let $D$ denote the set in $\mathbb{R^3}$ lying above the cone $z=\sqrt{x^2+y^2}$ and below the plane $z=4$. Set up the following integrals over $D$ as iterated integrals in cylindrical coordinates. You should think about which ones you can evaluate. (e) An integral representing the volume of $D$." What is the significance of setting up an integral representing the volume of $D$? AnonymousThu, 24 Jul 2014 09:42:04 -0500http://calc3.askbot.com/question/158/
