WebJun 13, 2024 · Assume phi = 0 is the x axis. The distance from the origin to the side is delx/2, and denote this by b. If the square were an inscribed circle of radius b, then the integral would just be 2*pi*b. But the square is a bit larger. Draw a 45 degree line from the origin to the upper right corner to make a triangle.
