>Summary: Plot leaves range with jacobi functions

Initial Comment:
Hello, 

I am working with jacobi elliptic functions with both 2d and parametric graphs and am finding they leave the domain when I use these functions under multiplication.  I believe the numeric package is running out of memory or the plotter makes some similar error.  How do I fix this, or how can it be fixed?

specifically try jacobi_dn()*jacobi_dn() with two frequencies (one about one tenth the other) for times exceeding 48.

This reliably causes the graph to spiral out of control and I was wondering if there was a fix.
