Let D be a lamina (a thin plate) occupying the region in the xy-plane that is in the first quadrant, between the circles of radius 1 and 4 centered at the origin. Assume D has constant density which you may take as a unit value. Complete these tasks: 1. Draw a graph of D. 2. Compute the mass of D (which will be the same as the area because the density is equal to one). 3. Identify a line of symmetry in D which will help with Step 4, below. 4. Compute the center of mass of D. I recommend that you use polar coordinates. 5. Go back to your graph of D and plot the location of the center of mass you just found.

A thin rectangular plate coincides with the region defined by 0 ≤ x ≤ π, 0 ≤ y ≤ 1. The left end and right end of the plate are insulated. The bottom of the plate is held at temperature zero and the top of the plate is held at temperature f(x) = 4 cos(6x) + cos(7x).
