Understanding Limits and the Number e

The video tutorial explains how to evaluate the limit of (1 + 1/n)^n as n approaches infinity, which equals the mathematical constant e. The process involves setting the expression equal to y, taking the natural log of both sides, and applying logarithmic properties to simplify the expression. L'Hopital's Rule is then used to evaluate the limit, leading to the conclusion that the expression approaches e as n becomes very large. The video also demonstrates this with numerical examples, showing how the expression gets closer to e with increasing n.
