The hint gave away everything. As soon as I read it my first thought was, "Oh, therefore adding an element doubles the number of subsets. All the existing subsets, plus each of them with the new element appended." So elegant.
Yaa, but for me it was more like I thought in my mind like this should work this way but clicked on video too see some even better proof that I can explain easily with words
I know I am a year late to this video, but Mr. Eddie Woo, if you ever see this, I just want to say thank you so so much, this definitely clarified this proof for me.
BTW binary arithmetic can be used to list all the subsets of a set. 0 means an element is not included in the subset, 1 means it is. Then count in binary eg 000, 001, 010, 011, 100, 101, 110, 111. Adding another element adds another binary digit which can be 0 or 1, thus doubling the number of subsets.
When introducing sets and subsets as a concept, you could have also related it to combinatorics since you had just refreshed that topic recently. Number of subsets in an n-set == sum of (n choose k) over range (0
lol.... so if one never seen a1, a2, a3...... / forgetting that resolution.... this is fantastic deductions at home, with fully understanding a question, and not letting pressure get to one.... and completely unique solution.... anyways it's awsome wish I saw something like this.... when I was in high school, would have aced fundamental math...
@@MichaelPiz No problem. Eddie has a video actually on his second channel where he talks about what how he records himself doing his lessons. ua-cam.com/video/5H9HzWboGp4/v-deo.html
Sir can you teach class 8 also in. Our area there is no best teacher I love study but I Found you so please start the class 8 It will really helpful for us students

Yes, looks complicated, but it's actually quite simple and elegant like you said

Pretty helpful

And I should have just waited for the next video...
What is the reason for taking the number 2 as BASE in all these examples ? Like 2^2, 2^3, 2^4 etc.

Sir please make a vedio of square and squares root
hi, i m from Bangladesh. 1 question this topic- why every power set contain empty set??
A small but pertinent correction: "the subsets i̶n̶c̶l̶u̶d̶e̶ _comprise_ subsets without l and with l"
6:55 that really looks like a doughnut(torus in topology)
What software are you using here? I could use it myself.
Thanks.
He uses an app called Notability. You can get it on the app store.

hey eddie! please read this comment! i want you to make some video on geometry! please!
search for the topic on his old videos, he has a lot and probably made what you need already
@@harutodoroki9918 thankss
perfectly explained!

*OBJECTION!*
Eddie, you just removed {} from the subsets for l=k+1
No, it's still there, as one of the original subsets from k.
There are no duplicates in a set.
he writes so beutifully &&&&&&&&&&&&&&&&&&& is a good cool pro explainer

Sir how can someone like me who is really bad at math and hate mathematics can Learn and understand Mathematics easily ???
By not being Indian. You have too much competition
I wish u were teaching in Delhi!
We have better teachers in India you just need to look around
اول
Bla bla go to subject directly
