comment Why the method of separation of variables works?
@ChrisWhite There are theoretical and mathematical physicists here who might know the answer to my question and who might not be following math stackexchange regularly. I want to maximize my chances to get an answer so I posted my question here and there. Sorry for offending anybody.

comment A little integration paradox
Interesting. I do not remember that is written in my calculus books, not even a warning :(

comment A little integration paradox
Yeah got it thanks. So the antiderivative must be continuous across the domain of integration to be able to substitute with the integral limits, right?

comment Where is the flaw in evaluating the following integral?
Excellent explanation, thank you so much. I am wondering why such subtleties are not taught in calculus courses? Do you know any book that cover similar subtleties?

@cardinal Please point out where it was used incorrectly as this is exactly my question.

@J.M. $dy=\cos\theta d\theta$ where $\cos\theta=\sqrt{1-y^2}$
