Elliptic integrals
hi everybody,
I put in the Prime Software Library a first attempt to make a program to handle Elliptical integrals (1st, 2nd and 3rd kind). It calculate: ell1F(x, k) > F, Elliptic integral of first kind ell2E(x, k) > E, Elliptic integral of second kind ell3β(x, k, n) > β, Elliptic integral of third kind But it needs to have some controls to avoid singular values and other issues. More, it could be expanded to calc also sn(), cn(), dn() [sometimes called amplitude sine, amplitude cosine, delta amplitude] and other parameters... In that program k is the "eccentricity", n (only for 3rd type) is a number called "characteristic" of the various curves. The program handle the "incomplete" integrals. For now, to attempt the complete ones, put x=1. I invite to collaborate and make a stronger and more stable and useful program, if you want. Thank you! you're welcome.
