Evaluate the following integral by converting it to cylindrical coordinates: ∫(-3 to 3)∫(0 to sqrt(9-x^2))∫(0 to 9-x^2-y^2) sqrt(x^2+y^2) dz dy dx
Determine whether or not the following series converges. ∑_(k=1)^∞▒8k/√(k^2+5)
A piece of a broken plate was dug up in an archaeological site. It was put on top of a grid, as shown in Figure 1.15, with the arc of the plate passing through A(7,0), B(1,4) and C(7,2). Find its center, and the standard equation of the circle describing the boundary of the plate.
