For the region R below, write JR f d A as an iterated integral in polar coordinates. F4 With a = b -2 and d -3 URfdA = Safe f dA, where dA = Note: Use t for # in your expressions.For each of the following, set up the integral of an arbitrary function f(r, y) over the region in whichever of rectangular or polar coordinates is most appropriate. (Use t for d in your expressions.) (a) The region - 110 With a 0 , b = 5 c = 4 and d = integral = fa fe f(xy) dy dx (b) The region (1/sqpt(2),1/sqrt(2)) -1 1.0 With a 0 b C = 0 and d = 1 integral = Ja le /(rcost,rint) d r dt
