Tetration FAQ Discussion

[Gottfried]

Code:

-- What does f o g mean?

We use the iteration paradigm.
Given two functions f(x) and g(x), then this is a short-form for f(g(x))

Note, that f o g =/= g o f  in the general case (Non-commutativity)

-- What does f°h o f = f o f°h mean?

If the special case

    g(x) = f°h(x)

is given, then

    g(f(x)) = f(g(x)) = f°(h+1)(x)
