According to Maple, the series expansion of about is (EDIT: You can derive it by starting with the Taylor series for centered at and using long division.)

Since we're integrating over values close to 1, is approximately .

so

As approaches from the right, is much greater than . You can include it if you want. You'll still get the same answer.

It is fairly easy to verify that for we have that and so . It follows that . Note though that the LHS is just and . The conclusion follows from the Squeeze Theorem.

Thanks DREXEL28. Every thing is OK!. But only, your inequalities should be strictly and they are correct for .
