Talk:Elliptic rational functions

Is this based on cd(u,k) or cd(u,m)?

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

"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

" 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)

I removed it. If people need to read it, they can read it here. 84.226.214.17 (talk) 22:56, 8 December 2019 (UTC)
