This video covers three essential theorems for the AP exam: the Extreme Value Theorem (EVT), the Intermediate Value Theorem (IVT), and the Mean Value Theorem (MVT). Each theorem is explained in terms of its conditions and applications, particularly in the context of the AP exam. The video emphasizes the importance of understanding these theorems for multiple-choice and free-response questions, providing examples and tips for their use. The EVT requires continuity, the IVT also requires continuity, and the MVT requires both continuity and differentiability. The video concludes with practical advice for applying these theorems in exam scenarios.
