Rolle s theorem khan math. Rolle s theorem is a special case of the mean value theorem. Rolle s theorem talks about derivatives being equal to zero. Suppose ƒ is a function continuous on the closed interval a b and that the derivative ƒ exists on a b. Assume also that ƒ a ƒ b.
Then there exists a c in a b for which ƒ c 0. Rolle s theorem has three hypotheses. In other words if a continuous curve passes through the same y value such as the x axis twice and has a unique tangent line derivative at every point of the interval then somewhere between the endpoints it has a tangent parallel to the x axis.

It contains plenty of examples and practice problems on how to find the valu. This calculus video tutorial provides a basic introduction into rolle s theorem.
