Let f be continuous on the interval [0, b). Show thatA = f(x) / f(x) + f(b - x) dx = b / 2 Hint: Let A1 = f(u) / f(u) + f(b - u) du. Note that A1 = A. In the above integral, make the change of variables u = b-x and let A2 equal the resulting integral. Then, determine the value of A1 + A2 and use it to determine the value of A.
