For each of the following, set up the integral of an arbitrary function f(I, y) over the region in whichever of rectangular or polar coordinates is most appropriate. (Use t for 0 in your expressions.) (a) The region (4/sqrt/2);4/sqrt(2)> -110 -1 With a = , b =[ c= ], and d = integral = fa fad (b) The region 18 -1 1.0 With a = ]. b = c=], and d = integral = for
