Hi Bret. Your videos have proved to be very informative. So, can I assume that if the set in consideration covers the metric space, then it is open? To give an example, if X=( (0, 1), de), instead of R, and when the set in consideration is [0, 1], then it is assumed to be open?

but... the open cover in green for [0, 1] has no finite subcover since if you remove any one of the 3 green lines its not a cover anymore so how is [0, 1] compact

Is not (-1, 2) is an open cover of (0, 1) just like it is for [0, 1] ?

thanks . so the interval must be open for set to be open cover.

Nice video..but still hv some doubt.abt the finite subcover which condition for compact set.can u give a example of compact set with this property..sry I could nt explain it perfectly. Hope u understand my doubt

It was that simpler!!! Why are textbooks so complicated.
