Is this based on cd(u,k) or cd(u,m)?
[edit]From the page for Jacobi elliptic functions, it says "The second variable might be given in terms of the parameter m, or as the elliptic modulus k, where k^2=m". Is this equation using k or m for the second parameter?
The discrimination factor is not the lowest but the largest value
[edit]"According to Mathworld, the source of this article, the discrimination factor Ln(\xi) is not the lowest but the largest value Rn(\xi,x) can have for |x|>= 1" — Preceding unsigned comment added by Furyer (talk • contribs) 10:07, 26 August 2020 (UTC)
Unclear sentences in the introduction
[edit]
" I thought, to be a rational function it is required that a condition Ｋ'(1/L_n) / K(1/L_n) = n K'(1/\xi) / K(1/\xi) to hold, here K'(k) = K'(\sqrt(1-k^2))."
This must be clarified. — Preceding unsigned comment added by Ndcroos (talk • contribs) 16:43, 14 September 2019 (UTC)
