Characterization of Limits: Techniques and Examples

This lecture covers the characterization of limits, including techniques for calculating limits and various examples. It explores the definition of limits, the behavior of functions near a point, and the calculation of limits using different methods. The instructor presents corollaries related to limits, such as the behavior of functions as they approach a specific value. Examples are provided to illustrate the concepts discussed, including limits of trigonometric functions and the area of disk sectors.
