Open Set with 9 Examples- In Hindi-{Neighbourhood & Limit points}-B.A./ B.sc Hons (Math) 1st Year

[@anjumshah8042]

Very nice teaching mam ......keep it up👍👍👍

[@ArchanaSharma-in5vv]

Mam, jab aap closed interval le rahi hai tab aap end points ko consider kar rahi hai aur isliye woh sab open set nahi no rahe hai par agar hum end points na le toh closed intervals bhi open set hi ho rahe hai ... Mujhe ye samaj nhi aaya

[@learnmatheasily]

Closed interval me end points hote he , open interval me nai hote

[@Sanuvatsa6195]

Why empty set is an open set? Not understood clearly. Can you please elaborate.

[@learnmatheasily]

Because there does not exist any point in empty set of which it is not the neighbourhood.

[@ramabansal6502]

There is any difference between open set and open interval

[@learnmatheasily]

yes. every interval is am open set but converse need not be true. watch video.

There is an example which is open set but not open interval

[@ramabansal6502]

I am confuse because every open set contain a nbd. Which is an open interval

Good one...could you explain why are we not taking interior point as number that exist at open bracket? I watched many videos but not clear with this point....for example open set (1,4) is there and 1 is not interior point then this not an open set. Could you please help me to understand this?
