- This video references "Intro to Real Analysis" by Bartle and Sherbert Fourth Edition. For more details related to the context of this video, see section 2.1.
The book has this as Section 2.1 Exercise 2(b). In this video, we rely on facts from 2.1.1 Algebraic Properties of R, as well as the lemmas (1), (2), and (3).
Thanks and enjoy the video! - Hry
