      Is this the same form that is linked in the description of your other videos?

      @@kabirbelgikar7095 Yes. I figure that most people don't read descriptions, so I put it in the comments.

      @@mathemaniac Ah okay, I asked because I was about to fill this in and wanted to make sure that I wouldn't have two submissions to my name.

    I always find Combinatorics harder than Calculus.

      100%. Calculus seems to be dealing with a lot of standard equations and substitutions. Meanwhile this is core problem solving!

      same, combinatorics are boring which makes them hard. Geometry is fun so never had problems with it

      Saaaaame, combinatorics just won't fit in my brain. But I'll make it.

    1:10 i dont get it, i mean at that point then theres only one founding principal, addition. As multiplication and inclusion/exclusion are based in or strongly tied to addition.

    At 2:42 , is the amount gain only is not AB $ , I think that E$ should not be there ?
    Well , great video , earlier I didn't heard of combinatorics but now I had a good idea of the perspective , thanks for the smooth animations and a good language/ sentence sequence to make us understand .
    Sorry , after rewatching , I got it that why there is E$ , as that amount is the amount that cashier haves already or say previously .
    Thanks

    3:15 so it would be....
    2 possible variations of the queue. (if we have 4 people in it, 2 borrowing and 2 depositing)
    not sure tho if you know better, comment :D

      You are correct.

      For any even n, would there be n/2 ways to do it? E.g with 8 people there would be 4 variations

      @mathemaniac  3 ปีที่แล้ว +5

      As far as I know, no. If it is actually solved, the author does a pretty good job at hiding it from public view.
