SEAMIC_Functions: Derivatives IV

In this video the speaker explains the concept of critical points in calculus, emphasizing that a critical point is where the derivative is equal to zero or does not exist. The speaker provides two examples of finding critical points using polynomial functions, one with a degree of 2 and another with a degree of 3, demonstrating how to calculate the derivative and set it equal to zero to find the critical points. The video concludes by mentioning that the next step is to classify these points as maximum or minimum, which will be covered in the next video.
