comment Regarding the connected component of $|1/J| < 1$ containing $\infty$
Yes, I do. That is pretty much what I have stated.

Do you know why the integral of any derivative along a closed path on the elliptic curve is going to be zero?

I do not see how it is a Legendre function. Can you elaborate?

@sranthrop You are using vol. 2. As far as I know vol. 1 is not on archive.org. Use the link to vol. 1 in my question. You should be able to preview the entire book.

@sranthrop I would really appreciate your help. There are three relations at the top of p. 34. The derivation starts at the bottom of p. 33 right after (3).

answered If $\{a_n\}$ and $\{b_n\}$ are Cauchy, then $\{a_n + b_n\}$ is Cauchy.

Because they are arbitrary real numbers $> 0$.

comment What are the practical applications of the Taylor Series?
@littleO Have a look at Einstein's famous energy-momentum relation, which is not very difficult to derive. For a particle at rest, the momentum $p$ is zero, so we get $E = mc^2$. If $p \approx 0$, then $E \approx mc^2$.

Thank you. I will have a look.
