The lecture explains how to simplify Big O notation by removing non-dominant terms and constants. It covers the analysis of a function's complexity, emphasizing the importance of identifying the dominant term. The process involves understanding nested loops and their impact on complexity. The lecture concludes with a preview of rare complexities, such as Big O of N factorial, which are less commonly encountered.
