Hello!

I browsed through the thread titles, but could not find anything related. I really apologize if this has already been asked before on this forum, but, here we go:

How can I rigorously prove that, for every natural n, the limit of x tetrated to n when x approaches 0 (through the positive side) is equal to 1 if n is even and 0 if n is odd?

I tried to prove through induction, but I never manage to conclude the proof. I also searched for it, but never found the proof of this

affirmation. It is stated on this article:

https://math.osu.edu/sites/math.osu.edu/...ration.pdf (page 5), and it says "evidences on the next section", but I still couldn't work it out.

Thank you.

Well I suspect you are on the right track. The point 0 is inside a period two fractal is shown in the following red disk.

Thank you for your answer. I tried to investigate these fractals, but I still couldn't solve it. What do you exactly mean the point is inside a two period fractal? And how does that relate with the limit? (I'm sorry if my question sounds too elemental).

The colors are for signed area as it approaches and doesn't approach white as much because of how much color there is

The limit is as many x as there are regions like numbers like complex numbers and the boundary is the graph which has an x
