Problem 5/18
• Use polar coordinates.
• Can either use a differential strip (be careful about centroid coordinates) so that you integrate
once from 0 = 0 to 0 = π/2 or integrate twice along r and then 0.
r = k₁+k₂0
• Notice there is a relationship between k₁, k2 and a given that r = a at 0 = 0 and r = 2a at
0 = π/2.
