Consider, in the xy-plane, the upper half disk of radius R, with temperature u governed by Laplace's equation, and with zero-Dirichlet B.C. on the (bottom) flat part of the disk, and Neumann B.C. ur=f(theta), on its (top) curved boundary.

(a)Use the Method of Separation of Variables to completely derive the solution of the BVP. Show all details of the procedure, and of your work. Do not start with with the eigenfunctions, the are to be derived. The final solution must be summarized and circled at the end of your work, showing the final complete expression for u(r,theta) and any coefficents and necessary conditions for f(theta).

(b) Obtain the complete simplified solution of the BVP above, with R=2 and f(theta) = 100.

A cake is shaped like a hemisphere of radius 2 with its base on the xy-plane. A wedge of the cake is removed by making two slices from the center of the cake outward, perpendicular to the xy-plane and separated by an angle of phi. A. Use a double integral to find the volume of the slice for phi = pi/3 B. Now suppose the cake is sliced by a plane perpendicular to the xy-plane at x = a >...
