What is the uncertainty in the speed of an electron whose position is known to an accuracy of 1.5% of the hydrogen atom radius? Assume that the radius of the hydrogen atom is 53 pm.
Super grateful for your work :-) I’m 16 and graduated HS this May and I am considering majoring in mathematics. I’ve been learning a lot of new topics including abstract algebra to see if I really want this, and your content makes this so much easier since sometimes books really don’t make sense. Question: Is this an *implication* of Lagrange’s theorem?
exquisite💙
In 10:02 you set n = 0, why?
Isnt every set an improper subset
The bar means given that
maybe it is obvious bc a, n, and b are all defined as ints, but should we also say a-nb exists in the nat nums to use the Well ordering principle
Can you please suggest me that book?
How did you get 6co(g) because you had 9cp(g) on the reactant and 3co(g) on the product side how did you get 6co(g)
Thank for video. Do you know how to find generator <r,f> of dihedral group D3 ? D3={e,r,rr,rrr, f,rf,rrf,rrrf}.
😮
Cayley's Theorem please
using a simple example of urs i was able to understand in 5 mins what i have been trying hard to study for a week thanks
please what software are you using for the teaching, the screen recording and the on screen writing, please I like it and wouldn't mind if you could introduce it to me
Hey man, I'm seeking this same thing. Please, plug me in if you get any software that works. Thank you.
Thank you so much for this. You saved me a lot of trouble
Thanks for this
Units modulo n? More like "Ultimately magnificent lecture; thanks again!" 👍
Hello sir. Can you please solve this one. R = Z×Z defined by nRm off nm≥0.
❤ You made Abstract Algebra looks like elementary arithmetic! Thank you so much😅😊
😮
esa musica jajajaja :v
THANKYOU SO MUCH!!
Love the content, eerie ass music, you should change it or replace it with your own narration in the future
I've been choosing random ambient music without thinking about it too much. I figure that people can mute it if they don't like it, but yeah, this one is particularly eerie. I'd like to start adding narration--just working on figuring out a good setup.
Omg! Just found out about your channel and it helped me a lot in enhancing my knowledge about groups, subgroups, and cyclic groups. Appreciate the very detailed proofs, Sir. More videos, please! This might be too much but I'm hoping that this month, you can create practice problems for Cosets, Normal groups, and quotient groups too.
Thanks, I'm glad that I could help! I plan on making more videos, so stay tuned. And yes, I would definitely like to cover those topics.
I learn alot from you, Thanks
Glad to hear that!
But why aren't you talking in your videos, everything is fine right?
Everything is fine. I just wanted to make a bunch of videos quickly and it's much easier to make them without having to edit the audio. I might make more "talking" videos again in the future when I have more time.
@@learnifyable I really hope the best for you, Thank you for everything you did.
Our saviour at abstract algebra is back ❤❤
Haha it's great to be back!
Very usefull,!!
Thank you!
just good lectures
Thanks, I'm glad that I could help!
thanks ,
No problem!
Thanks, that was nice. My book and videos I've watched so far didn't have this step in this video, and it was quite nice to see cosets as equivalent classes.
I agree, I think it makes sense to think about them this way.
My king
Awwww thank you!
Thank you
You're welcome
Totally helped me for my high school seminar. Amazing explanation
That's great! I hope that the seminar goes well.
@@learnifyable it did. Thank-you!
OMG YOU'RE BACK!!!!!! I'M SO HAPPY RN!!!
Awwwwww thanks!
The triumphant return
Woo-hoo!
Why is u2 not equal to the identity?
The notation can vary, depending on which textbook you are using. Here is a video that sums up the notation that I use: ua-cam.com/video/8cUiLMqNfHg/v-deo.html
What is delta 1 and delta 2 in the D4 chart?
They refer to reflections of the square about the diagonal.
@@learnifyable ah ok
Thaaank you so much
I'm glad that I could help!
what book do you use teacher , please
I recommend: A First Course in Abstract Algebra by Fraleigh Algebra Pure & Applied by Papantonopoulou A Book of Abstract Algebra by Pinter
@@learnifyable thanks
WAIT. NO. COME BACK. I HAVE A 58 D:
so u just used the d variable for no reason?
Your channel is the best for abstract algebra!
Found you here
@@Fjokuns Eiiii. FJ is cooking😂🔥
Chapter 2
i have gone through many videos on generators and cyclic groups and this is the only one that was actually helpful
How would you solve a similar question to this but only the total amount and number of coins is given, and you are asked to find the number of nickels, dimes and quarters.
Thanks a lot❤❤❤❤
Sorry new to abstract algebra so if this is wrong please correct for the second example (i composite f)(a) =i(f(a)) since i is acting on the image of f(a) which is in the set B wouldn't i also have to from the set B -> B?
Really good, ❤️🙏
The colour that you wrote on board is the same it's not visible
Thank very much, this was incredibly helpful.
