Hopefully express trains will become popular in America soon, anyways, Lovely video, in fact, it can’t possibly be expressed just how helpful this channel is
What is the difference between a limit point, an accumulation point, and a cluster point? I have seen all 3 terms used. If anyone can clear this up, you certainly can!
My professor did the same sine example but he made a notation of the subsequences, i.e. s_4k-3, s_4k-2, s_4k-1 and s_4k but I'm struggling because I don't understand how to find these notations by myself. Can you help me? I'm not sure how clear my question is.
It’s kind of an art, with practice it will become clearer, there is no set way to explain this, to be honest. Your prof probably used that notation because 2pi is 4xpi/2
@@drpeyam I believe i get it now. Thank you a lot! That just one sentence in the end made me realize it. Also I feel honoured to get your reply for some reason🤧 Thank you!

Sir...what are the limit points of the set {cosn: n is any natural number}?
Nice video Peyam. After watching it, I get why the thumbnail is a bulls eye lol :)
Thank you very much !!
Ok. Thank you very much. Neat but not evident.
