Real Analysis 6 | Supremum and Infimum [dark version]

[@shatadal_das]

It's a great playlist for Real Analysis with high quality content. But when I searched about real analysis, youtube didn't show me this playlist.

Thanks! I don't know how to change that :D

[@Mr.V2720]

why is the infimum of empty set = +infinity
can the infimum of a set be greater than its supremum?

[@brightsideofmaths]

Only for the empty set :)
