Advanced Calculus I, Part 3, Completeness Axiom, Supremum, Infimum

This is the third of a series of videos dealing with single variable calculus topics. We cover the supremum and infimum of sets. We discuss the Completeness Axiom. We will show the existence of square root of a nonnegative real number.

3:44 Supremum and infimum of (0, 1)
9:30 Existence of infimum using the Completeness Axiom
