Bob Wilson mentioned this in a pink box comment, so maybe he has tried it.
My question is, will it help with my constant headaches?
These headaches occur when I have a lot of terms of a sequence,
and I want a formula that will say something like
a(n) is roughly ... without my having to do a lot
of curve fitting, least squares, etc.
And of course I'm especially interested in extrapolating the sequence
out to infinity.
For instance, I'm very interested in A280774, and the b-file
gives 25K terms. Is there any chance TableCurve 2D will help?
There is a definite supra-linear "curve", but the first differences
look like a sandstorm.
It sells for less than $1000 but it is not cheap; there is however a
free trial offer. I'm skeptical, but has anyone tried it?
