1. Consider the curve (in the plane) formed by: the line segment from (2, 0) to (5, 0), the part of the circle of radius 5 (about the origin) from (5, 0) to (0, 5), the line segment from (0, 5) to (0, 4), and the part of the parabola y = 4 - x2 from (0, 4) to (2, 0). Orient this curve so that the direction of travel on the first line segment is from (2, 0) to (5, 0). Calculate the flux across this curve (with the given orientation)
