Inverse Iteration
#1
Composition: f(x) o c = f( c )
Iterated composition (steinix-ankh): ☉f(x)☥^n_x = f(x)of(x)o...of(x) n times
Iterator-ankh operator: It aOb ☥ = ☉ aOb ☥^n-1_b |(b=a)|(n=b)
It a+b ☥ = ☉ a+b ☥^n-1_b |(b=a)|(n=b) = a+(a+(a+...a+b))|(b=a)|(n=b) = a*b
It a*b ☥ = a^b
It a^b ☥ = a^^b (tetration)
...etc.
It FoG ☥ = ☉ F ☥^G
Now, we know how to iterate operators. But I do not know how to iterate functions, or my question: What is the inverse method of iteration?
