And that's interesting about the ringing, it confirms the lack of a viable asymptotic here even without looking at the complex graph. So it would seem that the "cheta" method is not a good method for extending tetration.I'll have to try out that Pari/GP package. I agree, the "cheta" method is not a good method for extending tetration, and I also agree that $\theta(x)$ is not analytic. But it tells us something about tetration, that fact that tetration for two different bases can be made to ring. There is an approximate sexp base conversion constant for large numbers, but the ringing means it is only approximate. The ringing for base e, and base eta, it is 0.08% from min to max. For cheta, and e, (or any other two sexp bases greater than $\eta$) there is a 1-cyclic conversion factor, such that as integer "n" increases, $\text{sexp}_e(x+n+\theta(x)) = \text{cheta}(x+n)$ for sexp_e, cheta $\theta(x)$ varies in the range -0.58432+/-0.0004 And there's still a couple of more interesting things I'm trying to figure out. But actually, the only bases for which I know how to generate reasonably accurate slog/sexp are base eta, and base e. Also, I can generate pretty good approximations for sexp for bases between eta and maybe 1.6 or so. It would help a lot if I had a Taylor series, for example for base 2, to verify some of the patterns I'm seeing. The phase and amplitude patterns hold for bases between eta, and 1.6, and also for base e. I'm sure someone must have a link to Andy's slog solution Taylor series results... - Sheldon « Next Oldest | Next Newest »
