The video tutorial, led by Aidan Gonzalez, explores the concept of exponential decay through the lens of the COVID-19 pandemic and vaccine rollout. It begins with an overview of the pandemic's impact and the introduction of vaccines. The lesson then delves into the mathematical principles of exponential growth and decay, using COVID-19 as a case study. Aidan explains how to model exponential decay mathematically and analyzes real-world data to evaluate the vaccine's effectiveness. The tutorial concludes with a discussion on the factors influencing the decline in COVID-19 cases and the role of vaccines.
