comment Measure : $μ^{*}(G\bigtriangleup A)=0$.
@O.B.D.A. That's too much for people like us who just started measure theory .

@user113576 May be this could help : $\mu(A \cup B) \le \mu(A) + \mu(B)$

@DanielFischer I don't know if $\mathbb Z[e^{2\pi i / 3}]$ is a UFD ?

comment Equal integral but only one of them converges absolutely .
Sorry, that was right . That means Baby rudin has a mistake . By the way i still wonder if two integrals are equal does that imply that if one is absolutely convergent then the other is also . I am confused because baby rudin says that even if two integrals are same one may converge absolutely and the other may not . :-/

you have forgotten to integrate $\cos x $ again , the first equality after "Notice that " doesn't hold .

Does that mean the two expressions are unequal in my question ?

The Babyrudin says that "sometimes" we can apply integration by parts to the indefinite integrals.
