comment differentiable structure on mobius strip
Okay. But just one more question (I'm very new to this DG and I'm not reading the book in order). Do I have to use the covering map $\epsilon:\mathbb{R} \to \mathbb{S}^1$ to construct an atlas on $M$?

Could you help me with the explicit construction part using $p$'s covering property?

comment Is there any “formula” that allows us make change of variables in surface integrals?
If I may, could you give me the reference textbooks for the above?

comment Proof of Cauchy Riemann Equations in Polar Coordinates
I think this is a standard approach though at its present form it is not completely rigorous. But surely this can be made rigorous by applying some MVT argument along one of the lines above.

revised If $x$ is a Lebesgue point of $f$, $f \in L^p$ and $f(x)=0$, then it is a Lebesgue point of $f^p$ where $p>1$ (finite)?
