OK, but maple defines a discontinuous function over the real line. Try plot(JacobiAM(x,sqrt(3/4)),x=10..20); plot(arctan(JacobiSN(x,sqrt(3/4)),JacobiCN(x,sqrt(3/4)))JacobiAM(x,sqrt(3/4)),x=10..20);
MMA, on the other hand, gives a continuous increasing function.
Does it mean that maple implement the Jacobi Amplitude via the suboptimal formula?
