WebRolle's Theorem. Suppose that a function f (x) is continuous on the closed interval [a, b] and differentiable on the open interval (a, b).Then if f (a) = f (b), then there exists at least one point c in the open interval (a, b) for which f '(c) = 0.. Geometric interpretation. There is a point c on the interval (a, b) where the tangent to the graph of the function is horizontal. WebIn calculus, Rolle's theorem essentially states that any real-valued differentiable function that attains equal values at two distinct points must have a stationary point somewhere between them;that is, a point where the first derivative(the slope of the tangent line to the graph of the function)is zero.If a real-valued function f is continuous ...
