This is the first time I actually understood it this concept. And I've taken several undergrad and grad courses that have reviewed this question. Thanks
I had read the first explanation in a book and could not understand it. I really appreciate your second explanation, though. It makes things so less complicated. Thank you.
Nice sir you explained very sharp way ..I understood completely please make more videos on mathematics because I haven't any teacher as sharp as your teaching ...I really want to learn smartly and conceptually ty sir keep going
The best explaination I have heard for circle permutation ... I have Searched many places but can't the this explaination this thing was stressing me .... At last find every answer to my questions ... Thank you so much making this video I felt like crying
I always knew that when arranging n people in a circle, there are (n-1)! ways to do it, but never knew WHY. It's so important to know the reasonings, especially when it comes to combinatorics!! Thank you so much for this !!!
yes and its the case with most the students who are having maths subject but they dont really want it but its not the case with me.if i ask any of my classmate they be like its just like this we have to arrange a circle table as (n-1)! but they might never know why they are doing this but i always love maths and im curious why something like this happens i dont just need marks but more important i wanna know why why something happens.I believe everything is there for a reason it might be the most tiny reason ever but def their will be some reason so yeah i got it . i sawed his video for the first time and he cleared my problems very easily on the first try.
I think , this statment depends on the subject of tabel for example : if each seats of the table has different carrer so , in this case the arrangement still permutation….. why you think here in this way and in the same situation you don’t for example when when we have 5 red ball ,logically we have one arrangement of the 5 red ball, because we can’t observe the different of them….
Seems to me like changing position around the table is a major factor to differentiate where people are sitting (view angle, adjacency to various things like other tables or environment, etc), and so it shouldn't be divided out of the possible arrangements in my opinion, although I guess the idea is probably to just give an example the people in the class can better relate to.
I would like to argue that the number of ways to sit around a table is exactly the same as the number of ways to sit in a line. In a line you could have A,B,C,D,E. A is effectively sitting next to E (as in the circle). It’s just that line circle A and E have been pulled apart by a small distance. It certainly cannot be that statistics is based on slight differences in proximity, could it? If in the circle scenario, you move any two seats apart by even a small distance you no longer have a circle but you now have established a curved line...and oddly have changed number of ways from 24 to 120 by this simple displacement. I hate that there needs to be any more than two equations nPr and nCr to solve any comb/perm question, so, I am seeking the barest-bones generalizations that will allow the previous two equations to be sufficient to solve any comb/perm work problem. I am very interested in your thoughts on this. Thank you!
The thing that is different is in a line, there is a first chair and second chair and so on. Like how a person at the corners gets a window seat. In a circle, even if all the people move one seat to the right, it is basically the same arrangement as you still have the same people on your right and left as before.
Sir pls solve this Let f(x) = a0 + a1x + a2x 2 + · · · + anx n where ai are non-negative integers for i = 0, 1, . . . , n. If f(1) = 21 and f(25) = 78357. Determine f(5)
The option to rotate the table seems arbitrary. You could say the exact same thing on a linear list - you can rotate it once and "lose" a factor of 4. Why would you decide to rotate the table? It's not the actual number of ways to sit people, but just another condition you set in the original problem, which is actually 4!
any one who is really here to learn math knows how well this guy teaches
For real
This is the first time I actually understood it this concept. And I've taken several undergrad and grad courses that have reviewed this question. Thanks
Man your school must be sht. No offence to you of course.
After 26 years old, finally i realized how it came from.. 😄
Eddie Woo, you are the best!!
love it when they teach us WHY the math is done that way and WHY is it like that, instead of just us getting taught HOW to do the maths
Your last example made it super easy to understand. Thanks. You made my day! 🙏

I LOVE the way Eddie explains!!! - Thanks sooo much
Hi,Eddie, your explanation make the problem so easy!
Beautiful explanation. Life saver!!
This guy teaches math better than any teacher in my whole country
Thank you 🖤🖤
Thank you! Your explanation was so simple yet so clear!
this man is a genius ❣️
Your explanation is literally AWESOME! Keep Going 👍✔️
Thank you so much your students are lucky to have you

Now how am I going to go back to my classes after ur amazing lessons😖
This explanation is so clear. Thanks!
Brilliant teacher I Love you 💕💕
Nice work .. Thanks man i understand circle permutation now
Wow, thank you! That was very intuitive
u r amazing
5:58 that's what my sir taught me but i didn't understand.
Now watching the whole video i get it.
Thanks Eddie, you're the man
I wish my math professor had this much enthusiasm while teaching
Sahi bole ho yaar
thank you for explain it.
now i'm feeling good understanding about this subject.
thank you sir, great explanation and teaching.
wooooowwwwwwwww im spechless, you are so good
Þanks for ðis upload. You make it look simple!
Thank you so much, you save my final exam
Nice elegant explanation
We really need this type of teacher in India! Not some cruel looking head cutter!
thank you , now i am good !

Please explain Circular Permutations with like(similar) objecta.

Love from India
Finally! I understand
Awesome
The way you speak make these easier to understand.
Enjoying
But we still have 4 ways to pick the person for the first chair, doesnt it make it 4! ?
thank you!!

Sir pls solve this
Let f(x) = a0 + a1x + a2x
2 + · · · + anx
n where ai are non-negative integers for i = 0, 1, . . . , n.
If f(1) = 21 and f(25) = 78357. Determine f(5)
Venkatesh infinity maths bro this is TH-cam not Brainly or doubtnut or socratic
Ya
The final equation becomes
f(x) = 5x^3 + 9x +7
Thus the answer is 677
God im so happy that Im asian love yu ♂
Thank you✨
Wow!!!
🤧IDK WHY AM WATCHING I ALREADY KNOW HOW TO DO IT..
Thanks :)
SEJM kinda sounds like "same" - what a coincedence
thanks bro
everyone here on their school accounts lol
Thank you
هلو من بكلوريا سوريا
Hey, that's not the same. My feng shui say i must sit on the north, not the south. So not the same.
Anyone in 2021?
Finally not an Indian xD
what is bro yapping about

Why you speak like you pissed with us
