i dunno what to do with this integral since both the limits are discontinuous: so so in evaluating the integral: which is infinite my answer seems to be divergent the answer at the back of the book seems to be

First and (drum-roll please!) So Thus . So And, of course, since the x = 2 limit isn't actually infinite we don't need to go through all that mess with the limit on it. -Dan
I don't know if this is correct. Calculate . Let . Now we have . Now take the limits when and and we get
