The video tutorial explains Rolle's Theorem, which states that if a function is continuous on a closed interval and differentiable on an open interval, and the function values at the endpoints are equal, there exists at least one point where the derivative is zero. The tutorial illustrates this with graphs and provides a detailed proof by considering three cases: constant function, maximum point, and minimum point. It emphasizes that the theorem guarantees at least one such point but does not specify how many or how to find them.
