Prove that every sequence has a monotone subsequence (ILIEKMATHPHYSICS)
This video references the book "Introduction to Real Analysis" by Bartle and Sherbert (Fourth Edition). The fact we are proving in this video is given by Theorem 3.4.7 and is called the Monotone Subsequence Theorem. Here is a proof of the result we use in the infinite case: • Prove that any infinite set of natural num... Thanks and enjoy the video!
