Iterates of exponent are evaluated through tetration tet and arctetration ate:
  +
  +
$y=\exp^n(x)=\mathrm{tet}(n+\mathrm{ate}(x))$ , thin lines
  +
  +
The corresponding linear combinations of the first and the second iterates of the exponent are defined with
  +
  +
$y=(2\!-\!n)\exp(x)+(n\!-\!1)\exp(\exp(x))$ , and marked with thick green lines.

Iterate of exponent (thin black lines) compared to the linar combination of $\exp$ and $\exp^2$, deawn with thick green lines.

Iterates of exponent are evaluated through tetration tet and arctetration ate:

$y=\exp^n(x)=\mathrm{tet}(n+\mathrm{ate}(x))$ , thin lines

The corresponding linear combinations of the first and the second iterates of the exponent are defined with

$y=(2\!-\!n)\exp(x)+(n\!-\!1)\exp(\exp(x))$ , and marked with thick green lines.

Description

This image is modification of figure 15.4 from the book Суперфункции, 2014 [1]

The English translation Superfunctions in 2015 yet is in preparation [2]


Evaluation of the natural tetration tet and the arctetration ate is described also in the Mathematics of computation (2009) and in the Vladicavkaz mathematical journal (2010) [3][4].
