Italians Say: Boh? Futuro di Probabilità

How do Italians express doubt? How do they communicate that something may have happened or probably happened? Actually, this is very simple grammatically, and it can be emphasized with a word that is very fun to say: Boh? This little expression will get you sounding very Italian in no time

Short Proof of Bolzano-Weierstrass Theorem for Sequences | Real Analysis

Every bounded sequence has a convergent subsequence. This is the Bolzano-Weierstrass theorem for sequences, and we prove it in today's real analysis video lesson. We'll use two previous results that make this proof short and easy. First is the monotone subsequence theorem, stating that eve

Multidimensional Bolzano Weierstraß

In this video, I prove the celebrated Bolzano-Weierstraß theorem in n dimensions, which says that a bounded sequence in R^n must have a convergent subsequence. This is the most important fact in analysis, and a lot of nice results follow from it Bolzano-Weierstraß: https://youtu.be/PapmU
