Hi group,

I'm trying to numerically determine the solution of an equation whose
coefficients are of the order 10^-100 or less. I've been running into
all sorts of errors relating to MaxIterations and step size but so far
I haven't been able to find any useful information in the Mathematica
book. If you're interested in the notebook i'm using, you can find it
here:

Thanks
