Power series intro | Series | AP Calculus BC | Khan Academy

[@Jnoel608]

wow just in time..... we were studying this in class and needed more intuition. great video!

[@Alive4Metal]

great video, it puts into perspective the weird language, such as "the series is centered at" , good intuition

[@extremelyhappysimmer]

@4:38 would love to hear about those finance applications of power series.

[@WheatleyOS]

The entire video it felt like he was getting to something, and the he just forgot what the whole video was originally about and cut it short.

[@DM-su6li]

Every video I've watched on power series feels the same. You think it's about to make sense and then the video ends.

[@kdmorgan300]

Thank you for your videos. They are excellent.

[@susankraft3487]

This doesn't say how to find the radius and interval of convergence of a POWER SERIES. It just discusses geometric. What is supposed to happen to the arbitrary constant?

[@GOODBOY-vt1cf]

thank you so much

[@aarjunmehta8205]

Excellent bro . Thx

[@tariquekhuwaja]

thanks sir, you are awesome

[@chesterholt5551]

Awesome thank you

[@aiicwyt6768]

Shoutout to Mr. Achille’s class!

[@andrewmontoya8511]

Did I ask?

[@rajcodes100]

I would love an explanation on perturbation theory as used in physics

[@salihatariqch9909]

Thnxs sir

[@Miumiu0404]

"What's exciting about this is.." lol I wish I could find excitement in this.

[@Laura-wj8ti]

Ikr I’m only watching this so I don’t fail calc lmao

[@gatord0g]

anybody know if there will there be a full series on discrete math?

[@6subswith0vids80]

I come from the future and he hasn't put up any discrete math yet

[@salihatariqch9909]

Yes

[@Arthanzar]

Please define "geometric series," and "common ratio;" and explain why; why did you do that? What is it for?

[@fc2p]

I think that's supposed to be a 3 at 1:00, since n=3

[@theodoreother7380]

I've been away for awhile. Great videos. I also have a question. (X^x=10(raised to 1,2,3,...)x) what is this property and do these numbers have a name? I am certain it falls out of base ten, since it shows similarity. Is that why it skips 5? The significant to 6 places first/second solutions greater than 1 seem to be: 3.059246 and 4.205869. Apologies for the format this question is posed, as the options to me are limited to present the question. Thank you.

[@kashmiri2786]

I am waiting from last 10 min. But the video is not opened... Because india government has banned 4 G speed here in kashmir ...

[@cigxhang486]

Is a over 1-x from a formula?

[@reab96]

Salman Khan, could you please make a video about Collagen Synthesis?

[@acid9381]

my ap calc bc mock exam tomorrow will be quaking.

[@derekdonahue5633]

I am still confused with why (x - a) is necessary? Can't it instead be a sum equal to one variable?

[@mudassarnazar8287]

sir why we expand the series?

[@Ry8901]

Title is misleading, only talks about the geometric series and not the power series in general

[@Gandalfbaws]

help me with this one plz. f(x) = 1/(3+x^2), i wrote it that it equals: 0 to inf sum of 1/3 * ((-x^2)/3)^n = sum of (-1)^n * (1/3)^n+1 * x^2n so the constant will be: (-1)^n * (1/3)^n+1 but my teacher complains and says that its wrong... why?

[@sebastianp994]

I would help you but that was 4 years ago, i'm sure you dont need the answer anymore

[@Gandalfbaws]

@@sebastianp994 haha i solved it but thanks

[@ToxicSpiker]

waste of time, doesn't explain how to find radius or interval of convergence for power series

[@leterpou7111]

+Hugh Jones no it is bullssshiittt even on the website the vidoes aren't ordered for every series, greatly confuses the shit out of people

[@waveform4d]

It's not rude if he's right. Misleading video title, waste of time.

[@shobhitmalhotra4079]

how to get the later videos to under stand power series

[@ian.ambrose]

@@waveform4d It's not even misleading, he did introduce to Power Series in the video.

[@Miriam-bl9ig]

What's wrong with this comment section

[@sandeepnain6901]

actually power series is nt explain in these video just explain the ratio test these video totally waste ur tme

[@kiwislice9760]

1st comment!

[@asmcriminaL]

great waste of my time... so how do you find the interval of convergence?

patrickJMT is better

Bullshit !

Hahaha I hate math

Heheeeee😓😓
