Investigation on the Concept of Limit Involving E by Exploring the Secret of Mr. Buffet
Abstract
This article uses problem-driven teaching methods to explore a mathematical class of important limit in course design. We first start with the story of Buffett’s wealth to gain students’ interest in the concept. We establish mathematical models based on the financial management issues and guide students to explore them. Then, through the analysis of the compound interest problem, solution with limit expression of the problem and its relationship with the natural constant e are obtained. Finally, in response to Buffett’s sentiment, we use this limit to analyze and explain the mathematical principles of investment issues and to lead students to think about their views of life and values, resulting in a positive influence on their life planning.
