Differentiate x^x^x^x

In this video, I showed how to differentiate x^x^x^x

[@ADWYETYATRIPATHYBEI]

It's been 6 years since I opened a Math book... and this vid just brought back memories of school and college days!!! You deserve way more subscribers

[@PrimeNewtons]

Thank you!

[@akiya9216]

The questions you do are normally quite easy for me and would be pretty boring to go through, but watching you do them is really enjoyable. Very very very fun, you are good at teaching :)

[@PrimeNewtons]

Maybe I'll step it up soon 🤣🤣🤣

[@et427gamer9]

I am in algebra two so this all goes over my head but I still enjoy it significantly! Cant wait to get to higher level math like this. I can tell you love the subject and that love will transfer to your students. Keep it up!

[@nengimotejaphet2565]

I usually feel shy watching your videos ’cause you’re so flirty😌😹 but this one! I can’t even lie you did this explanation better than organic chemistry tutor, and he was my go-to KZbin tutor! Guess who is my go-to KZbin tutor now🤭❤️

[@cherryisripe3165]

Everything seems so simple with your explanations and pedagogy. Thank you so much.

The best maths channel I found till date, I'm so interested in learning all these

[@rishichava355]

Thank you, you explain everything extremely well and make math very enjoyable!

[@nanasung2701]

thank you so much, i've been struggling with differentiation and i have a test tomorrow for it ♥️

[@ThenSaidHeUntoThem]

This is brilliantly done!

You are amazing proffesor You might be an excellent Hollywood actor as well I dont know how many subscribers you have, but beleive me, you deserve a lot more

[@justpassingbyy]

Bruh, you have such a pleasant voice.

[@ananthianandan553]

You are literally awesome ❤

[@kathieharine5982]

Excellent professor!

[@sunil.shegaonkar1]

I have problem with the last term at 16:16, it does not account for X^x, this term is not in y' but factored out. This is a multiplier of the greater bracket. Factoring increases stack of 2 to 3, but greater bracket has x^x which has No term in y'. Rest is wonderful, I had no idea how to find derivative of 3 stacked function

[@lukaskamin755]

So cool, I'm from Ukraine and we learn maths with slightly different approaches, though, of course, math is the same, no doubt. I definitely enjoy your videos, with such a hillarious attitude, and perfect clear language (being non-native English speaker, I can totally understand everything

[@Calcprof]

If y = x^x^x^x^......, then y = x^y, and differentiate implicitly. and solve. This gives y' in terms of x, y, and log x. You have to be a little careful of boundary values, but I think you can handle these. BTW: y can be easily expressed in terms of the Lambert W function y = - W(-log[x])/log[x]. Since W'[x] = W[x]/(x (1 + W[x])), this can be used to calculate y' and express it entirely in terms of x, log[x] and W[x]. (You have to be a little careful of which branch of the solutions of z = x e^x you have, but all of this can be sorted out.)

[@123qopsiznoq]

Thank you

"Why am I not multiplying? Because I don't want to"😂 This is like me also sometimes when I teach my friends and classmates

[@littlegrass320]

how do you solve x^x^x = 3 using Lambert W function

[@devcoachingclasses1]

Your 'Nice' word is very nice❤

[@user-xg1ch3zb8y]

Thank you very much for opening my eyes, Professor! so much appreciate in your way to explain and solve that question quite easily. Well if I could ask you about what is the differentiate of X^X^X^2x, what is it should be then?

[@jumpman8282]

Hi! The easiest way (in my opinion) to tackle this type of problem is to start by differentiating 𝑦 = 𝑥^(2𝑥). Taking the natural log of both sides, we get ln 𝑦 = 2𝑥 ln 𝑥. Implicit differentiation (chain rule on the left-hand side and product rule on the right) then gives us 1 ∕ 𝑦⋅𝑑𝑦 ∕𝑑𝑥 = 2⋅ln(𝑥) + 2x⋅1 ∕ 𝑥 = 2(ln(𝑥) + 1) (Note that we don't have to worry about 𝑥 = 0 in the denominator since 𝑥^(2𝑥) is not defined for 𝑥 = 0 anyway, so 𝑥 ∕ 𝑥 = 1) ⇒ 𝑑𝑦 ∕ 𝑑𝑥 = 𝑦⋅2(ln(𝑥) + 1) = 𝑥^(2𝑥)⋅2(ln(𝑥) + 1). So, 𝑑 ∕ 𝑑𝑥[𝑥^(2𝑥)] = 𝑥^(2𝑥)⋅2(ln(𝑥) + 1). - - - Now we can differentiate 𝑦 = 𝑥^𝑥^(2𝑥), using the exact same method. Take the natural log of both sides: ln 𝑦 = 𝑥^(2𝑥) ln 𝑥. Implicit differentiation: 1 ∕ 𝑦⋅𝑑𝑦 ∕ 𝑑𝑥 = 𝑑 ∕ 𝑑𝑥[𝑥^(2𝑥)]⋅ln(𝑥) + 𝑥^(2𝑥)⋅1 ∕ 𝑥 = 𝑥^(2𝑥)⋅2(ln(𝑥) + 1)⋅ln(𝑥) + 𝑥^(2𝑥)⋅1 ∕ 𝑥 = 𝑥^(2𝑥)⋅(2(ln²(𝑥) + ln 𝑥) + 1 ∕ 𝑥). ⇒ 𝑑𝑦 ∕ 𝑑𝑥 = 𝑦⋅𝑥^(2𝑥)⋅(2(ln²(𝑥) + ln 𝑥) + 1 ∕ 𝑥) = 𝑥^𝑥^(2𝑥)⋅𝑥^(2𝑥)⋅(2(ln²(𝑥) + ln 𝑥) + 1 ∕ 𝑥). So, 𝑑 ∕ 𝑑𝑥[𝑥^𝑥^(2𝑥)] = 𝑥^𝑥^(2𝑥)⋅𝑥^(2𝑥)⋅(2(ln²(𝑥) + ln 𝑥) + 1 ∕ 𝑥). - - - Finally, we can differentiate 𝑦 = 𝑥^𝑥^𝑥^(2𝑥). ln 𝑦 = x^𝑥^(2𝑥) ln 𝑥. 1 ∕ 𝑦⋅𝑑𝑦 ∕ 𝑑𝑥 = 𝑥^𝑥^(2𝑥)⋅𝑥^(2𝑥)⋅(2(ln²(𝑥) + ln 𝑥) + 1 ∕ 𝑥)⋅ln(𝑥) + 𝑥^𝑥^(2𝑥)⋅1 ∕ 𝑥 = 𝑥^𝑥^(2𝑥)⋅(𝑥^(2𝑥)⋅(2(ln³(𝑥) + ln²𝑥) + ln(𝑥) ∕ 𝑥) + 1 ∕ 𝑥) ⇒ 𝑑𝑦 ∕ 𝑑𝑥 = 𝑥^𝑥^𝑥^(2𝑥)⋅𝑥^𝑥^(2𝑥)⋅(𝑥^(2𝑥)⋅(2(ln³(𝑥) + ln²𝑥) + ln(𝑥) ∕ 𝑥) + 1 ∕ 𝑥). So, in the end we have 𝑑 ∕ 𝑑𝑥[𝑥^𝑥^𝑥^(2𝑥)] = 𝑥^𝑥^𝑥^(2𝑥)⋅𝑥^𝑥^(2𝑥)⋅(𝑥^(2𝑥)⋅(2(ln³(𝑥) + ln²𝑥) + ln(𝑥) ∕ 𝑥) + 1 ∕ 𝑥).

In general differentiation decrease the equation but in this case not applied

[@OmChouhan-ps6sk]

you have such a beautiful hat. from where did you get that?

[@josephparrish7625]

That was fun! Where do you find these crazy problems? Lol

[@PrimeNewtons]

Lol. Usually, someone sends me a problem like this.

[@Notking444.]

Can you make full concept clearing video of differentiation

[@luca_151]

would it be easier to say y = x*y, then ln y = y lnx, and then differentiate from there?

[@gdubbsboi1640]

Have you done videos on factorials? Would love to learn it from you.

[@PrimeNewtons]

I think I'll do factorials soon

[@roddos]

Great hat.

[@DSN.001]

are tetrations derivatable?

[@superiorjr154]

At what point does differentiation turn into tetration or vice versa

[@Deadpool-rw1pk]

I am writing this question before watching the video : i guess you are going to use natural log (since it more convenient to derivative ) ?????

[@user-vy6oc2cr5m]

Differentiate x ^^ x (^^ means superpower like ³3 means 3^3^3)

[@mehmetdurna3115]

Nice equation

[@aaditya8283]

Sir can you plz bring a video pf proper explanation of why e^x differentiation and integration is e^x always bcz your explanation are easy to understand😊😊 love you from India.

[@PrimeNewtons]

I already have that

[@souverain1er]

@Prime Newtons Your thinking is as organized as your writing

[@PrimeNewtons]

I hope that's a compliment because I'm still trying to organize my thinking 🤔

[@wavingbuddy3535]

i tried this myself and got the same answer but i wrote mine as: x^( x^x^x + x^x + x) * ( ln(x)^3 + ln(x)^2 + ln(x)/x + 1/(x^(x+1))) very satisfying video as usual, love your charisma when you're going through the steps

[@user-op6me3mr3w]

Help me please🙏 I've a arcsin(1/3) and I need to find that, but I need an exact value. I mean I needn't a number like 0,3472.....I need an expression. For example: Arcsin(1/4(√5-1))=π/10 Arcsin(1/2)=π/6 Arcsin(1/3)=??? Arcsin(1/3)=?

Hey, just saw your video about tetration, it would be x with 4 in left top corner

[@Yesandwhoareyou]

How seductive

[@lirich0]

Comment for the algorithm

[@flowingafterglow629]

You what would have been a really cool way to end that video would be to evaluate the derivative at some point (not x = 0 or 1, though). Something like, 2. This is the slope of the line x^x^x^x at x = 2..... It's a beautiful expression, but it's fun to remember a use of the derivative.... (maybe in the next video set y' = 0 and find critical points....)

[@leoniii1247]

Woah this is way harder than I thought... I thought the answer was x^x^x^x * x^3 * ln(x) and I got no idea why the video is that long...😂

[@pritamsur1926]

Sir please solve my indefinite integration:- integral of(32-x^5)^(1/5) dx

[@jensberling2341]

Is there a mistake? You said 2^2^2=2^4. Then you said; 3^3^3=3^27. That must be a misprint. Pls, responds, Dr. Newton.

[@jumpman8282]

A power tower is evaluated top down. However, some calculators interpret 3^3^3 as (3^3)^3 instead of 3^(3^3), so you've got to be careful.

[@theupson]

i know of no finesse for the actual labor of the problem, but the whole construction is more legible, maybe, if you start with y = s^t^u^v s=t=u=v=x and use multivariate chain rule. if that's out of bounds, switch the first three "x" for e^logx. y=exp(logx * exp (logx * exp (x*logx))) and the disassembly via chain rule and the product rule subtasks flows pretty naturally
