The Lambert W Function can be implemented in your calculator using Newton's Method. To find W(A), the equation to solve is: f(x) = x*exp(x)-A = 0 (1) f”(x) = (x+1)exp(x) And f(x)/f'(x) can be written as: (x-A/exp(x))/(x+1) Finally, the recursive formula for Newtons Method is: X = x-(x-A/exp(x))/(x+1)) From (1) we have x*exp(x) = A or ln(x) + x = ln(A); x = ln(A)-ln(x); x ~ ln(A); ln(A) is a good initial value for the Newton Method when A>1, if this is not the case we use A. If your calculator can handle complex numbers ln(A) is a good initial value too. You can find that W(-i*pi/2) ~ 0.5664173303 - i0.6884532271 and exp(-W(-i*pi/2) ) ~ 0.4382829367 + i0.3605924719 you can compute i^i^i^i... a few times in your calculator and verify that it converges to this number.

As far as I know, it has been shown that there exists a unique piecewise smooth monotonic function satisfying f(a + 1) = b^f(a) for all complex a provided that 1/e^e < b < e^(1/e), consistent with Schröder's equation and Abel's equation, which is agreed to be the standard definition of tetration. However, that such an f exists does not mean there is closed-form expression for it. i^^i may or may not be defined, but if it is, then it, for all practical intents and purposes, cannot be simplified or calculated other than with some numerical algorithm for computers. As far as I am concerned, I would say we are far from solving the problem of tetration.

@Yusuf Onur, Nope, sorry, that's not correct. What he is asking, is not a tetration (a.k.a. "power tower"). Instead, he is just asking about an expression of the form (..((((i^a)^a)^a)^a)...)^a with a being equal to 1/i = -i. This simplifies to i^[ a*a*a*a*...*a ] , which will be non-convergent. i'th root of the i'th root of the i'th root ... of the i'th rooth of i = = ⁱ√( ⁱ√( ⁱ√( ⁱ√( ⁱ√( ... ⁱ√( i )..))))) = (..((( i^[1/i] )^[1/i] )^[1/i] )^[1/i]... )^[1/i] = (..(((((( i^[-i] )^[-i] )^[-i] )^[-i] )^[-i] )^[-i] )...)^[-i] = i^[ (-i)*(-i)*(-i)* ... *(-i) ] which is either i^(-i) , or i^(-1) , or i^(i) , or i^(1) , and hence isn't convergent. In other words: it's the limit of the sequence a[n+1] = (a[n])^(1/i) , starting from a[0] = i . But as it turns out, z = lim{n-->+infinity} a[n] doesn't exist.

Thanks for the great video! I have a quick question: Since i is imaginary and i^i=e^(-pi/2) and i^i^i = i^(a real number), each iteration of the power tower makes the result alternate between real and non-real. Would the result you got still be valid, or would the limit of the power tower not converge? Thanks again for releasing great videos in your spare time!
@angelmendez-rivera3514 жыл бұрын
PlasmaCrab _ The power tower does converge, so his result is valid. However, proving it does converge is quite a pain in the ass, and probably outside the scope of this comment section. You might wanna check Knesser's result, though. If you search that, you might find something satisfactory.

youssef yjjou lim 2^x (x -> +♾) = +♾, this is correct. However, you have to be careful. In some contexts, it may be useful to say 2*2*2*2*••• = lim 2^x (x -> ♾). However, in the theory of sequences, as well the theory of extensions of the real numbers, we tend to talk about those two expressions as different quantities. Think of it this way. If there exists a quantity that is bigger than all real numbers, called M, and if we consider f(x) = x |-> 2^x : R & {M} -> R, then f(M) =/= lim 2^x (x -> M). This is just a formalism, but the point is that the limit alone doesn't allow you to say the expression cannot take on a finite value.

Complex powers represent a combination of rotation and scaling in the complex plane.

Thus they formal a spiral that funnels down toward the point of convergence. This is often what convergent sequences look like in the complex plane.

Hey, I was wondering, since i=e^[i(Pi/2)], could you subsitute the i in the exponential by e^[i(Pi/2)] ? So you'd get: i= e^[e^[i(Pi/2)](Pi/2)] And most importantly, if you repeat this an inifinite amount of times, is it still equal to i ? And since i never appears on this infinite exponential, does it become a real number equal to i? This might be very poorly explained, and Im sure I made some mistakes here and there, feel free to ask me more and correct my errors.
@angelmendez-rivera3514 жыл бұрын
Adeal's TASes i = e^(πi/2) = e^[πe^(πi/2)/2] implies that there is a sequence to consider here. Namely, a(n + 1) = πe^(πa(n)/2)/2, with a(0) being the parameter that one need to be careful about. If a(0) = 1, the sequence diverges. In fact, the sequence only converges if |a(0)| < 1, or if a(0) = i or a(0) = -i. Assuming the sequence converges, one can obtain the limit by setting πe^(πz/2)/2 = z, and then solve for z. However, in the theory of divergent sequences, one can find the value of infinite expressions without regard for their convergence. In this case, it would be possible for the expression (e^π/2)^^♾ to be i.

Allain Cumming Each element in the sequence is multivalued, so the limit of the sequence, which is the infinite power tower, is also multivalued. i^i itself is already multivalued. Anyhow, I do not know if the theorem has a name, but the theorem states that if 1/e^e < |a| < e^(1/e), then the sequence (1, a, a^a, a^a^a, ...) converges, and the limit, which is equal to a^a^a^•••, is -W(-ln(a))/ln(a).

But from the very beginning you could also write Z^i = Z, and this is simply not solvable. In other words, first you need to prove that Z is a nice limit which is finite and could be found. I doubt this is true.

Does this work if you do i^i^z=z? Because technically it's true
@angelmendez-rivera3514 жыл бұрын
Balázs Bartha Yes, it is true, but it does not work because the equation i^(i^z) = z is impossible to solve analytically.

Do you have the right to do i^i^i^i... = Z = i^Z ? It looks like the mistake with the infinite sum of 1 when you can demonstrate that 1 = 0 with S = S +1 etc...
