Evaluate the line integral OF . dr by evaluating the surface integral in Stokes' Theorem with an appropriate choice of C S. Assume that C has a counterclockwise orientation when viewed from above. F = (x2 - y2, z2 - x2, 12 - 22) C is the boundary of the square |x| s 14, |y| s 14 in the plane z = 0. . . . Rewrite the given line integral as an area integral over the appropriate region of the xy-plane. OF . dr = J J D dA R Evaluate the integral. OF . dr = (Type an exact answer.) C
