1. (10 Points.) 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 rst line segment is from (2,0) to (5,0). Let f (x, y) = in V x2 + yz. Calculate the ux of V f across this curve (with the given orientation)
