Given x which you think is an algebraic number. Can you use Mathematica
to find its minimal poly?
The number I would like to test is:
x = 19.05962891397391285670091722808301086216...
I believe this is the root of either a quadratic or a quintic poly
P(x). Of course, with an approximate number x one can always find a
P(x) with large enough coefficients such that x is a root, but if you
can find one with "small" coefficients, then that might be it.
Any help will be appreciated.
P.S. I tried the "Integer Relations" applet at
http://www.cecm.sfu.ca/~aszanto/IntegerRelations/ but either there was
a glitch in the server or my comp and I couldn't access it. :-(
