So I have been revamping the functions I use for tetration, and I recently solved all the mumbo-jumbo to use tetration as the function in the NaturalIterate function. So now you can do:
I'm still working on doing this for other bases, but this is enough to get an expansion of pentation about zero.
What follows below is InverseSeries[...] of the output from above. In other words, the above gives the coefficients of the base-e penta-logarithm about (0), and the following gives the coefficients of the base-e penta-exponential about (-1).
So, what I'm wondering is, how do I turn this into an expansion about 3i?
Code:
<<Tetration`
