> Hi, John
I rec'd some answers to the questions you had yesterday
regarding high order polynomials:
Mathematica can handle high order polynomials (100+ for
example) and find their multiple roots, though you will
in most cases be limited to numeric roots, not symbolic
or exact (rational). (Also, this can take a fair amount
of time/memory; it will vary depending on the polynomials, etc.)
About the infinite loop/sum of rational polynomials:
Our tech guy, John, did not know anything that would cause
this; he asked if you were just adding some polynomials, or
using some other function, such as Solve, that could have
large intermediate expressions that would take a very long
time to evaluate, giving the appearance of an infinite loop.
If it is a simple addition, it should be reported to support at wri.com,
maybe there is a bug fix, or maybe it is know and will be fixed
shortly, or maybe it needs to be made known.
Hope this helps!
