This question is taken from Q.49 P. 181 of the textbook; source attached below! 00:00 Introduction 00:48 Formulas 01:47 Proof a with Method A 07:04 Proof a with Method B 11:57 Proof b with Method A 14:43 Proof b with Method B 16:37 Graphical Explanation As a current undergraduate biomedicine student, I'm just trying to make these videos to support people, and myself as well! I'll watch these back when I study, so I'm basically teaching myself too! The examples that I've used for this video are directly from my textbook, BioCalculus. This is such an amazing book, making learning calculus way more fun! Source: Stewart, J., & Day, T. (2015). Biocalculus: Calculus for life sciences. Cengage Learning.
