Rolle’s Theorem and Critical Points - Calculus I
This video delves into the notion of Rolle’s Theorem, which is a theorem that guarantees the existence of at least one critical point within a certain open interval, for functions which adhere to particular conditions. A critical point is a point at which the derivative of a function is zero. To restate this, a critical point is a point at which a function has a horizontal tangent line, and the slope of the tangent line is equal to zero.
