Analyzing Concavity and Implicit Differentiation

Mr. Bean guides students through the final lesson of unit five, focusing on implicit differentiation. The lesson covers determining if a curve is increasing or decreasing, analyzing concavity using the second derivative, and finding maxima and minima with implicit functions. The video emphasizes applying these concepts to implicit relationships and equations, preparing students for the next unit on integrals.
