Mean value theorem defines that a continuous function has at least one point where the function equals its average value. The theorem states that the derivative of a continuous and differentiable function must attain the functions average rate of change in a given interval.

The mean value theorem mvt recall that the intermediate value theorem ivt states that a continuous function on a closed and bounded interval attains every value between the values at the endpoints at at least one point in the interval. On rst glance, this seems like not a very quantitative statement. B the other mean value theorem which i always perhaps erroneously call the intermediate value theorem, or the waterleveling theorem is as you stated it. I know how to prove it using another technique, but how do you do it using mvt. The mean value theorem is similar to the intermediate value theorem except that the mvt says that there is at least one point in the interior of the. As the name first mean value theorem seems to imply, there is also a second mean value theorem for integrals.

Mean value theorems play an important role in analysis, being a useful tool in solving numerous problems. If xo lies in the open interval a, b and is a maximum or minimum point for a function f on an interval a, b and iff is differentiable at xo, then fxo o. The mean value theorem first lets recall one way the derivative re ects the shape of the graph of a function.

A real life application of the mean value theorem by. Its kind of neat, but what youll see is, it might not be obvious to prove, but the intuition behind its pretty obvious.

You might have, for example, a discontinuous function, so the theorem is not applicable at all, but in some such cases the conclusion will still hold. If so, what does the mean value theorem let us conclude. It is one of important tools in the mathematicians arsenal, used to prove a host of other theorems in differential and integral calculus.
